F-1.1 Pre-feasibility Study for Outer Ring Road

Japan International Cooperation Agency (JICA), the Directorate General of Highways (DH) and South Province Government agreed to conduct a pre-feasibility study (the Pre-F/S) for the Outer Ring Road in addition to the F/S roads.

Table F-1.1 shows those F/S and Pre-FS Roads.

F-1.2 Arterial Road Network Plan for the Mamminasata Metropolitan Area

(1) JICA 1989 Highway Development Plan

JICA conducted the “Ujung Pandang Highway Development Study” in 1989 (“the 1989 JICA Study or Plan”) for the target year of 2009. The urban arterial road network system in the Makassar Metropolitan Area was configured with five radial roads and three ring roads, as follows (also refer to Figure F-1.1).

Radial Roads: ・ Jl.Tol.Ir.Sutami ・ Jl. Urip Sumoharjo / Jl.Perintis Kemerdekaan ・ Jl.Boulevard Pannakukang and its east and west extension (Central Radial Road) ・ Jl.Sultan Alauddin / Jl.Gowa Raya ・ Takalar – Jl.Metro Tj.Bunga (South Radial Road)

Figure F-1.1 Road Development Plan by JICA in 1989

These development plans are well coordinated with the Spatial Plan of Makassar City. Makassar City has developed the arterial road network as recommended in the 1989 JICA Study and completed most of them by 2005, except Central Radial Road, South Radial Road (Tj Bunga-Takalar Road), Middle Ring Road and Outer Ring Road.

(2) Road Development Plan in Mamminasata Spatial Plan Study

The Mamminasata Spatial Plan Study reviewed the JICA 1989 Plan. It added two new road development concepts, Mamminasa Bypass and Trans-Sulawesi Mamminasata Road, to the 1989 highway plan (Figure F-1.2). A total of 268 km of roads were planned to be improved by the


F-3

target year of 2020 and the priority four roads (1 to 4 in the Figure F-1.2) are subject to the FS by JICA.

Figure F-1.2 Urban Road Network System Planned in Mamminasata Study

The Mamminasata Study deleted the northern part of the Middle Ring Road (Section 2) taking reservation of the Tallo River estuary environment and higher construction costs into consideration. The Mamminasata Spatial Plan did not recommend the Outer Ring Road and the Central Radial Road. However, a pre-feasibility study will be conducted as proposed by the South Sulawesi Province and Makassar City and agreed between DGH and JICA at the Inception Report stage.

(3) Road Development Plan of South Sulawesi Province

The original route of the Outer Ring Road in the 1989 JICA Study was a route connecting KIMA/Jl.Tol.Ir.Sutami (Jl.Tallo) and Sungguminasa (Kabupaten Capital of Gowa) crossing


F-4

Jl.Perintis Kemerdekaan and the central radial road.

The Outer Ring Road proposed by South Sulawesi Province in the 2003 – 3012 Spatial Plan has two accesses; one going to KIMA (Kel.Daya) and the other is an extension of it to the north bypassing the east side of the Hasanuddin Air Port and joining the national road as shown in Figure F-1.3.

(4) Plan of Makassar City

Figure F-1.4 shows the route of the Outer Ring Road in the 2005 - 2016 Spatial Plan of Makassar City. This road starts at Sungguminasa (Kabupaten capital of Gowa) and goes to the north through the dense residential area. Then, it passes through Kec.Manggara (Makassar City) and enters into a short stretch in Kec.Moncongloe inKabupaten Maros. After crossing the Tallo River, it is connected to KIMA at the Daya intersection as planned in the JICA 1989 Study.


F-5

The Outer Ring Road branches off approximately 2.5km before the Daya intersection and turns to the west through BTP (Perumahan Bumi Tamalanrea Permai), a new residential area and connects KIMA and Jl.Tol.Ir.Sutami.

Figure F-1.5 Urban Arterial Road Network System for Mamminasata Metropolitan Area

The JICA Study Team reviewed the Mamminasata Study on engineering and implementation aspects and made the following modifications and additions to it for the target year of 2023:

・ Modification of the northern and the southern part of Trans-Sulawesi Mamminasata Road route

・ Shifting of Mamminasa Bypass to the front of Mt. Moncongloe and Mt. Bogo (on the Makassar side)

・ Recovery of the Outer Ring Road as planned in the JICA 1989 Study ・ Recovery of the Central Radial Road as planned in the JICA 1989 Study ・ Recovery of Section 2 (northern extension) of the Middle Ring Road to connect to

Jl.Tol.Ir.Sutami by keeping an appropriate distance from the Tallo River to avoid negative effects to the estuary environment

・ Addition of an access road between a proposed satellite town and KIMA ・ Extension of the Inner Ring Road to the south and west through Losari Beach ・ Addition of the new Port Access Road ・ Addition of the Northwest Coast Road from Jl.Tol.Ir.Sutami to Tambua (Kab.Maros)


F-7

F-1.4 Traffic Demand Forecast for Outer Ring Road

The traffic demand estimated in the Mamminasata Study was reviewed to avoid over-planning of road facilities. The present traffic (2006) and the future traffic demand for the FS and Pre-FS roads are indicated in Figure F-1.6. The year 2023 traffic was estimated at 25,000 pcu/day (south of Sungguminasa) and 30,000 - 40,000 pcu/day at the middle part of the Outer Ring Road.

F-1.5 Development Concept and Alternative Route Planning for Outer Ring Road

(1) Function of Outer Ring Road

The Outer Ring Road is one of the important links in the Mamminasata Metropolitan arterial road network system and its expected functions are as follows:

・ Ring road to contribute to harmonizing urban development ・ Bypass for the traffic from/to the northern part and to/from the southern part of

Makassar City ・ Logistic route for the coming in and out traffic from/to the southern area of the South

Sulawesi Province to/from KIMA, Makassar Port, new industrial areas along Jl.Tol.Ir.Sutami

・ Reduction of traffic burden on Jl.Perintis Kemerdekaan, the Middle Ring Road and


F-8

Jl.Sultan Alauddin. ・ Connection between the north educational center (Hasanuddin University, Institut

Agama Islam Negeri, etc) and the south educational center (Hasanuddin University Technology Faculty, Universitas Islam Negeri Alauddin Makassar).

The Outer Ring Road and Mamminasa Bypass share the same road at their southern part to connect to Tj Bunga Development Area.

(2) Overall Plan

The Outer Ring Road consists of three parts. The northern ring is the part accessing to KIMA, Jl.Tol.Ir.Sutami and Makassar Port. The middle ring is a straight road section parallel with the Middle Ring Road, and the southern ring is a connection to Sungguminasa and Mamminasa Bypass. The road development concept has been established in accordance with these traffic demands. A 2-lane 2-way road is the basic concept required for the Outer Ring Road based on traffic demand and envisaged road functions. However, reservation of land for additional 2 lanes should be made for the sections where ROW acquisition is not difficult for the future widening requirements.

Three aspects (engineering, economic and environmental aspects) will be considered for the establishment of development concept and alternative route selection for the Outer Ring Road. The engineering aspect includes road functions, traffic demand and reduction of overburden on Jl.Perintis Kemerdekaan, matching with the existing flood control plan for the Tallo River. The economic aspect includes contribution to KIMA / new industrial development areas along Jl.Tol.Ir.Sutami, logistic support for the southern area development of the South Sulawesi Province and connection of the educational facilities located along Jl.Perintis Kemerdekaan with those planned along Jl.Malino. The major socio-environmental issues are land acquisition, resettlement and effects on wetlands (natural environment) along the Tallo River.

A road development concept and alternative route plans for the Outer Ring Road are shown in the following Table F-1.2 and Figure F-1.7. The Outer Ring Road will be planned in 3 parts; north section, middle section and south section. Three alternative routes for the north section, four routes for the middle section and four routes for the south section were established for comparison (refer to Attachment F.1 as to the detailed alternative route map).

Alternative 1

This is one of the current plans of Makassar City. The planned route is a connection from Alternatives 1, 2, 3 or 4 of the middle section to Jl.Perintis Kemerdekaan through the BTP (Bumi Tamalanrea Permai) road. The BTP road is a road constructed for housing developments and it was transferred to Makassar City (see right photograph）. However, as this road is narrow (5.0-5.5m width x 2 ways), it needs widening by sacrificing the median to provide a 6 m wide road.

It will not be appropriate for heavy vehicles to go to KIMA and Makassar Port through this road. Passage of heavy vehicles through the BTP road should be limited for avoiding negative effects (congestion, traffic accidents, noise, etc.) on the

residents staying along this road.

F-16

Dinas PU Makassar (Makassar City Public Works Department) has recently surveyed this route and drew a proposed road alignment (red lines in Figure F-1.13). This proposed route will not cause negative effects to the Tallo River environment if it is about 500-700 m away from the Tallo River.

Alternatives 2

This access passes through an open band of wetland located in the housing development area and is connected to the KIMA entrance. This open band is a ROW already provided by Perumahnas (National Housing Corporation) for about 2.5 km in length (Figure F-1.15).

Alternative 2 is the original plan in which the road is directly connected to KIMA through Jl. Daya (Figure F-1.16). However, it will not be easy to acquire the required ROW as a local market exists and many houses are densely located along this road for about 400-500 m (Figure F-1.17).

KIMA


Jl.Daya Raya


Figure F-1.17 Alternatives 2 and 3 for Outer Ring Road Access to KIMA

The existing road connection between Jl.Perintis Kemerdekaan and Jl.Tol.Ir.Sutami is a partly 4-lane and partly 2-lane road. The 2-lane road section should be widened to a 4-lane road as soon as possible. As most of ROW has already been secured, it will not be much difficult to acquire it.

Alternative 3

The JICA Study Team established an alternative route which passes behind the shopping building (Pusat Niaga Daya) and connects KIMA and Jl.Tol.Ir.Sutami (Figure F-1.17) without requiring much resettlement. However, as this is too near to the Jl.Daya Intersection, it will not be appropriate from the engineering viewpoint.

(5) Middle Section

This is the section between the Tallo River and Jl.Hertasning. The road passes through or near the flood retarding area of the Tallo River (refer to Figure F-1.18). Four alternative routes were planned for this section as shown in Figure F-1.19.

Alternative 1 route crosses over the Tallo River and runs along its west bank to the south. It is influenced by the flood control work planned for the Tallo River. The new roadway embankment and river dyke for flood control could share their functions as indicated in the standard cross sections (refer to Figure F-1.10).

Alternative 2 is same as Alternative 1 but it goes to the south passing through the wetland and new residential areas. Some resettlements are unavoidable.

Figure F-1.19 Alternative Routes for Middle Section of Outer Ring Road

The route in Alternatives 3 and 4 passes through the east part of the Tallo River flood basin (Kabupaten Maros and Gowa). Alternative 3 crosses through the middle of the flood retarding basin while that of Alternative 4 bypasses it. These routes, especially that of Alternative 4, seem to be too far from the Middle Ring Road while too near to Mamminasa Bypass. As a flood area of 7 km x 2 km exists between the east and the west banks of the Tallo River, the route of the Outer Ring Road would be better aligned on the west side. Among those alternatives, the JICA Study Team recommends that Alternative 1 is the most appropriate plan from the engineering viewpoint.

(6) South Section

There are several control points to be considered for selection of the appropriate route for this


F-19

section, including lakes/swamps, Chinese cemetery, State Islam University under construction (Figure F-1.20), crossing point of the Jeneberang River, traffic congestion and dense residential area around Sungguminasa. Four alternative routes were planned for the south section (Figure F-1.21).

F-20

Alternative 4 is the original plan in the JICA 1989 study. The Outer Ring Road was planned to connect Sungguminasa (Jl.Gowa Raya) in the original plan. However, as the access area to Sungguminasa is densely occupied by residential houses, it will be very difficult to acquire the required ROW. Alternative 3 is a plan to connect the Outer Ring Road to Sungguminasa by reducing resettlement.

Alternative 2 is to make a ring road system by using the existing provincial road (Malino Road). Widening of the Malino road from 2 lanes to 4 lanes is necessary considering the future traffic demand. This route seems to be appropriate for the medium term.

Alternative 1 is a plan to locate the Outer Ring Road at approximately 3.0 km east of the Sungguminasa / Jl.Malino intersection where resettlement requirement is far less compared with other alternatives. It extends to the south passing over the Jeneberang River (Figure F-1.22) and is connected to the Mamminasa Bypass. From where it uses the Mamminasa Bypass then joins the national road and ends at the Tj.Bunga – Takala Road near the west coast. This plan will contribute to reducing traffic jam at Sungguminasa and Alternative 4 is the most appropriate plan in the long term from the engineering viewpoint.

F-1.6 Evaluation and Recommendation on Alternative Routes

(1) Alternative Route Evaluation Method


F-21

An Initial Environmental Examination (IEE) was carried out based on the existing data, the data collected for the FS roads, and site reconnaissance survey. Multi Criteria Analysis (MCA), which comprises engineering, economic and environmental elements (IEE results), was used for evaluation of alternatives. The Middle Ring Road and Outer Ring Road, both new ring roads, are expected to contribute to logistic flow between the international port / the new industrial areas and the southern area of South Sulawesi Province.

(2) North Section

Alternative 1 is one of the routes planned in the Makassar City Spatial Plan. This route is advantageous compared with others as it is connected to Jl.Tol.Ir.Sutami using the existing road (BTP road) and a new industrial area road, which is constructed by an investor. As the road section between Jl.Perintis Kemerdekaan and Jl.Tol.Ir.Sutami is constructed by the investor, expenditures by the public sector can be minimized. The Alternative 1 route can also be used for the access of the Middle Ring Road. As ROW acquisition for Alternative 2 route is difficult, it will be a mid-term to long term plan. Alternative 3 is not recommendable as it needs a new intersection near the Jl. Daya intersection. Hence, the JICA Study Team recommends Alternative 1 for the short term and together with Alternative 2 for the medium and long terms. Results of Multi Criteria Analysis (MCA) are given in Table F-1.3.

(3) Middle Section

The route of Alternatives 1 and 2 is located at the west and Alternatives 3 and 4 at the east of the Tallow River flood basin. As a flood retarding band of 7 km x 2 km is located between the west and the east banks, the road route should be on the west (Makassar) side taking the envisaged road functions into consideration.

Alternative 1 is advantageous compared with Alternative 2 as it requires less resettlement and its embankment can share with the flood control dyke. Results of Multi Criteria Analysis (MCA) are given in Table F-1.4.

F-24

(4) South Section

Implementation of Alternative 4 recommended in the JICA 1989 Plan is difficult as the Sungguminasa town development was faster and required ROW acquisition is now difficult. Alternative 3 reduces resettlement compared with Alterative 4 but still requires considerable resettlement.

Widening of the Malino Road from 2 lanes to 4 lanes is necessary either with or without the Outer Ring Road to meet the traffic demand in the future. Alternative 3 is a ring road system by using the Malino Road and seems to be appropriate for the medium term.

Those Alternatives 2, 3 and 4 do not much resolve traffic congestion at the Sungguminasa/ Malino Road intersection as shown in Figure F-1.23. These also do not meet the required road functions for the Outer Ring Road as a bypass for the traffic from/to the northern part to/from the southern part of Makassar City and connection between the north and the south education centers.

Figure F-1.23 Crossing Point of Outer Ring Road at Jeneberang River

Alternative 1 could resolve those disadvantages though its initial traffic is low. Hence the JICA Study Team recommends Alternative 2 for the medium term and Alternative 1 for the long term (Table F-1.5).
