Veterans Memorial Bridge, Portland & South Portland, Maine

SEGMENTS, WINTER 2011, VOL. 56

Segment casting has begun for the Veterans Memorial Bridge replacement project (Fig. 6) connecting the cities of South Portland and Portland, Maine. The project consists of two variable depth, pre-cast segmental structures (Figs. 7 and 8) each approximately 1,600' in length built in the balanced cantilever method of construction. Spans range up to 250' in length and segment widths vary from 39'-9" to 45'-9".

Reed & Reed Inc. (Woolrich, ME) was awarded the design/build contract in February 2010. The $63.1 million proposal submitted by Reed & Reed and their lead design engineer, T.Y. Lin International (Falmouth, ME), was the lowest bid price of the three teams competing for the project and received the highest technical score from the Maine DOT. The design/build proposal included significant public involvement throughout the design process. A series of workshops were held in the spring of 2010 for members of the community to provide input on final design elements of the bridge important to pedestrians, bicyclists, and residents of the two communities.

Segment casting started in July 2010 at Unistress Corporation’s facility in Pittsfield, MA. The short amount of time from contract award to first casting required that segment shop drawing production, material procurement, and final design proceed concurrently. McNary Bergeron & Associates worked closely with the design/build team to provide a constructability review throughout the design phase. This review helped the team quickly finalize segment details that met the required design life of 100 years while maintaining the anticipated casting and segment erection schedules. McNary Bergeron is also providing a full construction engineering services package on the project.

Work on the foundations, abutments and piers is proceeding and super-structure segment erection will start in the spring of 2011. The bridge is scheduled to be open for traffic in July of 2012.
