Plain Street Bridge

TEC’s structural team provided engineering services for the final design and construction of the Plain Street Bridge (Br. N-23-017) over the Canoe River replacement project. The existing bridge consisted of three failing corrugated metal pipe culverts with substandard bridge railings.
TEC investigated many potential bridge superstructure types, but ultimately proposed adjacent precast concrete deck beams. Plain Street is in a flood plain, and the adjacent deck beams provided the shallowest structure depth, which allowed to maximize the hydraulic opening to the greatest extent possible. To minimize excavation and allow for an expedited construction duration, TEC proposed integral abutments founded on steel H-piles as the bridge substructure. The Canoe River is a popular local recreational area, so TEC worked closely with the town’s local boards and commissions to ensure that recreational use of the Canoe River would be maintained to the greatest extent possible during construction. TEC proposed the bridge construction with a road closure after demonstrating that a proposed detour route would not create significant impact to traffic. To reduce the bridge construction duration considering the road detour, the bridge design utilized accelerating bridge construction techniques with the use of precast concrete abutments, precast concrete deck beams, and precast concrete guardrail transitions. To also maintain the functional use of the Canoe River, the bridge construction was proposed in two phases with interim steel sheeting being the basis of the control of water and support of excavation systems. The new bridge also provided sidewalks on both sides in accordance with MassDOT’s Healthy Transportation Police Directive.

TEC led significant permitting efforts with the FHWA through NEPA for a categorical exclusion. Other permitting efforts include a De Minimis Impact Determination on 4(f) property, Massachusetts Department of Environmental Protection, USACE, Massachusetts Historical Commission, and the local historic board and conservation commission.

TEC also provided construction administration services throughout the construction phase of the project with the review of contractor submitted shop drawings, RFI responses, and coordination with MassDOT resident engineers.

Bridge construction was completed in the summer of 2017.
