ABP Funding
Budgeted $25M to re-deck bridge bridge
deemed beyond useful life.
Original Cost to replace in kind =approximately $52 million with no surface
street improvements
MassDOT once in a lifetime opportunityengage community and stakeholders to
explore solution that met mobility and

The Measures of Evaluation (MOEs)
Approach Taken to Caseys MOEs All modes, livability objectives, new measures
WAG Integral to the formation and evolution of the
MOEs developed over the 9 months Principles (fatal flaw), Goals, Objectives and Measures
MOEs used throughout the process and to evaluate
alternatives on their own merits MOEs shaped the alternatives (i.e., surface streets re-
designed for all alternatives rendering some MOEs
obsolete)

How can traffic operations be similar?
North-south traffic volumes unchanged betweenalternatives
At-grade offers additional improvements to critical north-
south link on South Street
Removal of Bridge only adds east-west through traffic tosurface streets (additional thru lanes provided at-grade)
All turning movements happen at grade regardless
7/31/2019 DAG Welcome Meeting
53/74
East West
Regional Travel
Regional travel times relatively unchanged for
overall trip Any in-bound delays at grade on New Washington
are offset by existing delays at Murray Circle
In fact, the new design of New Washington maymeter the travel times, providing more
systematic processing of traffic
7/31/2019 DAG Welcome Meeting
54/74
Local Diversions (cut-through)
Concerns on cut through focused on east/west
travel.
The At-Grade Alternative increases east/west
travel by only 30 to 90 seconds.
The travel times along alternate routes
(potential cut-through routes) are greater than
the proposed at-grade network
