ACCELERATED BRIDGE PROGRAM (ABP) TIME LINE DR
The historic $3 billion Patrick-Murray Accelerated Bridge Program represents a monumental investment in
Massachusetts bridges. This program will greatly reduce the number of structurally deficient bridges in the state
system, while creating thousands of construction jobs on bridge projects.
To complete this program MassDOT will rely on the use of innovative and accelerated project development and
construction techniques. As a result, projects will be completed on-time, on-budget and with minimum disruption to
people and to commerce.
Since 2008, the number of structurally deficient bridges has dropped from 543 to 482, a decline of over 11 percent.
Over the course of the eight year program, more than 200 bridges are planned to be replaced or repaired.

A COMMON PLATFORM FOR MOBILITY & LIVABILITY GOALS
MOBILITY: the ability to reach a destination and to use, choose and transfer modes
within reasonable time and costs. Mobility is higher when average travel times,
variations in travel times, and travel costs are low. The provision of multi-modal
opportunities is essential for good mobility.
LIVABILITY: the use of transportation investments to improve the standard of living,
the environment, and quality of life for all communities. Livable communities are
places where transportation, housing and commercial development investments
have been coordinated so that people have access to adequate, affordable and
environmentally sustainable travel options.
Guiding Principles:
•
•
•
•
•
•
•
•
Improve safety for all users.
Address a structurally deficient bridge.
Protect and respect the design for Arborway Yards.
Develop alternatives that meet ABP budget and schedule.
Adopt the principles of Universal Design (accessible and barrier-free design).
Strive to have an inclusive process for the sharing of information.
Improve quality of life for residents.
Integrate artistic elements in designs.
Goals:
• Improve roadway geometry to balance circulation for all modes and all users.
• Improve access and modal & intermodal connections locally & regionally
to promote existing transportation choices.
• Integrate sustainability into design concepts.
• Remove barriers for neighborhood and park connections and integrate transit
into economic centers and residential areas.
• Create a destination and sense of place and celebrate the area’s architectural,
transportation and open space history.
• Improve the visibility, connectivity and access to gateway open spaces.
