Wayland Concrete Bridge Replacement Route 20 over the Sudbury River

Project Manager: Joseph Gioioso
Engineer: Greenman Pedersen Co.
Client: Massachusetts Highway Department, District 3
Construction Cost: $4,900,000
Construction Schedule: January 2007 - October 2008

The Wayland Bridge project involved the replacement of the Route 20 roadway bridge over the Sudbury River in Wayland, MA. The project is located on the historic Boston Post Road, which was part of the United States’ first regular mail route in 1673 and Massachusetts’ first numbered state road in 1925.  The project included the installation of a two-span temporary panelized bridge to carry the vehicular traffic, allowing the closure and demolition of the existing bridge in one phase. Both the temporary and permanent bridges required steel sheeting cofferdams for water control, and H-pile foundations driven to depths up to 90 feet. The new bridge included Integral-style bridge abutments, six “bulb tee” style precast girders, each 110 feet long and weighing 60 tons, and a cast-in-place concrete bridge deck. The project also included rip rap revetment and wetlands plantings along the edge of the river and the bordering Great Meadows National Wildlife Refuge.
