Congress Parkway
Built in 1956
IDOT owns 10 movable bridges
Chicago owns 37 movable bridges
Trunion Bridge: A trunion bridge is a style of
movable bridge that rotates about a fixed
point.

Project Purpose & Need,
Scope & Schedule
Purpose & Need of Project
- Improve Bridge Condition & Load Rating
- Improve Public Safety (skid reduction, delineate lanes, off-
road crash mitigation (F-shape), lighting, surveillance, etc.
Scope of Work
- Rehab Bascule Bridge structural, electrical and mechanical
- Replace open grid deck with closed deck system w/skid
resistant surface
General Schedule – Two Construction Seasons
– EB (Inbound) Bascule Bridge - April 2010 to January 2011
– WB (Outbound) Bascule Bridge - April 2011 to October 2011

OVERVIEW
Rehabilitation Issues
• Bridge Rehabilitation
• Two Bridges
• Narrow Bridge/Lane Widths
• Post Office Constraint
• Boat Traffic
Alternate Routes
• Inbound / Outbound
• Peak Hours
Operational Concerns
• Inbound High Speeds
• Traffic / Ramp Volumes
• EB Spill-Over onto I-290
• Event Traffic Dispersion
• Incident Management

Congress Parkway Bridge
Traffic Control Considerations:
– Rehab work with bridge in open position
– Speed Limits - Inbound Freeway Speeds 35 MPH
– Traffic Volumes (139,000 ADT)
– Lane widths on Bascule Bridge
(4 lanes – 43 feet face to face)
– Lane widths under Old Post Office
(4 lanes - 38 feet wide/portal)
– Distance between Post Office and Bridge < 200 feet

Transportation Management Plan
• Traffic Control Plan (TCP):
Temp. Widening, Restricted Lane closures,
Incentive/Disincentive provisions, Detours/Alt Routes….
• Transportation Operations Plan (TOP):
Corridor/Network management i.e. signal timing, WZ Safety,
Incident Management, Enforcement/hirebacks…
• Public Information Plan (PIP): Media Outreach/DMS
Work Zone Mobility (3-08)

5 scenarios were evaluated during the Phase I Process
• Scenario #1: Maintain All Inbound Lanes; All Outbound lanes would be detoured
• Scenario #2: Provide Two Inbound Lanes and One Outbound lane
• Scenario #3: Provide Two Inbound Lanes and Two Outbound Lanes
• Scenario #4: Provide Two Inbound Lanes and One outbound for Stage 1 (2011);
Then Provide Two Inbound and Two Outbound lanes for Stage 2 (2012)
• Scenario #5: Same as Scenario 1; however work would continue through Winter
to Shorten Construction Season.

RSA- Defintion: A Formal, independent and comprehensive safety performance review of a road transportation project conducted by an experienced team of safety specialists to maximize safety of the roadway environment for all users.
Members Included:
• FHWA
• IDOT Central Office-Bureau of Traffic Safety and Engineering
• IDOT Central Office- Bureau of Construction
• Illinois State Police
• Chicago Police Department

RSA- recommendations :
Improve Signage and Striping, Unexpected Queues, Poor Pavement Conditions, Improve Pedestrian Signals, Coordinate Emergency Response, Repair Barrier Gates…
Most recommendations were executed in advance contracts or into the main contract.
Roadside Safety Assessment
Recommendations

15
Perferred Scenario:
Scenario 2: 2-Lanes In & 1-Lane Out• Similar To TCP utilized in 1980
• Provides Better Lane Shifts During construction
• Provides One Lane Outbound for Emergency
and Unfamiliar Users
• Higher Risk Lane Shifts Minimized
Other scenarios not preferred due to…• Scenario 3 & 4 (2-in 2-out): increases higher vehicular crash risk,
higher risk in substandard lane shifts, and substandard lane widths without lateral barrier offset.
• Scenario 1 & 5 (All in): does not provide outbound lanes for emergency/unfamiliar drive access and increase Ped./vehicle conflicts on alternate routes
Roadside Safety Assessment
Preferred Scenario

I-90/94 INBOUND RAMPS
I-90/94 ramps inbound closed due to capacity and safety issues
• Safety - Closed to eliminate merge maneuver within lane
shift/median cross-over
• Reduction in traffic from ramp closures will significantly improve
operations and safety along Congress Parkway
• Additional traffic load on Congress Parkway may result in back-ups
onto I-290 and at I-90/94 ramps,
• FHWA expressed concerns relative to back-up potential and effect
on safety along I-290.
Ramp Issues
Congress Parkway Outbound to I-90/94 ramps
• Ramps to I-90/94 will remain open however alternate route will be
designated to minimize congestion and provide travel time savings
