Hollis E. Jennings Bridge Replacement

This $5.5M design-build project used numerous Accelerated Bridge Construction (ABC) Techniques during the complete replacement of the Hollis E. Jennings Bridge, Padelford Street over Route 24 at Interchange 11 in Berkley, MA.

Padelford Street is a two-lane urban minor arterial with an approximate average daily traffic (ADT) of 6,500 vehicles/day. Route 24 is a limited access highway with an approximate ADT of 62,000 vehicles/day.

Based on the public involvement process, MassDOT altered their original scope of work which called for conventional staged construction (which could extend to two years) using the design-bid-build process. The Town had significant concerns regarding the project’s possible impact to school bus routes. Therefore, MassDOT implemented an accelerated construction schedule and limited closure of the bridge to a 6-week schedule, which also altered the proposed project delivery method to a design-build project.

The design build team’s technical approach utilized heavy lift installation with prefabricated bridge units (PBUs) in lieu of the Self Propelled Modular Transporters (SPMT) approach identified in the base technical concept, as it was determined to be more cost effective with less impact to the site and Route 24 traffic. With this approach, nearly the entire structure is comprised of prefabricated or precast elements in order to facilitate the reconstruction of the bridge within the designated 6-week window.

A time lapse video of the bridge replacement was developed by the contractor, MAS Building and Bridge.
