Municipality Groveland/HaverhillProject Bridge Reconstruction: Bates Bridge over the Merrimack RiverStatus 60% completeCost $49,750,000Description The project consists of the replacement of the existing Bates Bridge carryingRoutes 97/113 over the Merrimack River with a new bridge located approximately 60 feetdownstream. The existing bridge will remain in service during construction. The proposedbridge will have a movable span similar to the existing bridge. In addition to the 775 feet longbridge, the project includes reconstruction of the approach roadways in Haverhill and Groveland

and traffic signal and geometric improvements at the intersection of Groveland Street withLincoln Avenue in Haverhill and at the intersection of Groveland Street with Main Street nearElm Park in Groveland. Cianbro Corporation from Pittsfield, ME is constructing the project.

The primary elements of the roadway work include excavation, grading, installation ofbituminous pavements, curbing, sidewalks, highway guardrail, pavement markings, relocationand/or adjustment of existing utilities, and installation of traffic signal systems.

The primary elements of the bridge work include the construction of a new movable span bridgewhich includes the installation of drilled shaft foundations, reinforced concrete piers, a structuralsteel superstructure, a concrete filled grid deck, a moveable bascule lift section, concrete

abutments on pile foundations and retaining walls. Temporary cofferdams will be used duringthe construction of the work, which will include removal of the existing bridge.

Current Project Status The majority of work within the river continues to be staged from twoworking barges that are in place to support heavy construction activities. The contractor hasfinished concrete placement for the southeast and northeast retaining walls/caps and for piers 1,2, and 4. The contractor continues to place cement concrete and reinforcing steel for pier basesand walls in cofferdam 3. Electrical conduit is being installed from the north abutment bridgeutility bays. Riprap has been placed to finish grade at the abutments in areas where the new steelgirders have been installed.

The existing bridge remains closed to marine traffic due to structural deterioration. MassDOThas requested the Coast Guard approve a request to maintain the draw as inoperable until suchtime as the new bridge is in service and the existing bascule span is removed.
