District 4: Deck Repair

Project Overview:

• Work to date on this job has consisted of mobile concrete bridge deck repairs on a nightly basis using rapid setting concrete and volumetric mixers. This special type of concrete has a much faster set time than conventional concrete which allows the bridge to be open to traffic before the morning commute.
• SPS has addressed countless emergencies under this job which ensures the traveling public’s safety as well as minimizing potential delays if the bridge had to open at a reduced service for a long period of time.
• MassDOT issued much needed repair work on critical bridges in Wilmington and Waltham. Once the concrete repairs were finished, the bridges were given a new hot mix asphalt wearing surface to protect the deck and structural members below.

Key Challenges Overcome:

• There were multiple challenges with finishing critical repair work during summertime deadlines. For example, repair work was performed at the Elmer Bumpis Bridge in Somerville, all sidewalks were repaired before schools started for the year. The bridge has an immense volume of foot traffic being in the middle of the City.

Interesting Facts / Figures
