East-West Parkway and Related Imporvements

Location: Abington, Rockland and Weymouth, Massachusetts
Contract Value: $31,239,000
Project Dates: October 2010 – September 2012


The former South Weymouth U.S. Naval Air Station was closed in 1997, and the site is being redeveloped into a 1,400-acre village-style live/work/shop/play community with expected final completion in 2017.

This Project involves the design and construction, on a Design-Build basis, of a new cross-Base parkway, including three vehicular bridges.

The project also includes the construction of new passenger platforms, a new parking lot and other improvements to the MBTA’s South Weymouth Commuter Rail Station, and construction of a ‘shared use path’ through the development site.

Also required are improvements to Trotter Road in Weymouth, roadway widening and improvements to Weymouth and Hingham Streets in Rockland, and the ramps from Hingham Street to Route 3. 

Barletta was the Design-Build entity selected by the South Shore Tri-Town Development Corporation to build their $31.5M East-West Parkway and Related Improvements project, which was completed in September 2012.  The former South Weymouth U.S. Naval Air Station was closed in 1997, and the site is being redeveloped.  Barletta and our design team members brought the owner’s vision through the design and construction phases, ultimately providing a new tree-lined, cross-base parkway, including three vehicular bridges, a shared use path, pedestrian bridges, and wetland replication areas, wildlife management areas and the restoration of a stream channel.  The parkway also included 1900 feet of a mechanically stabilized earth (MSE) wall which ranged in height from 5 feet to 20 feet.  Utility work required much attention to detail in design and coordination, as it included the relocation and removal of US Navy base electrical power, and installation of new electric, traffic signals and street lighting, water, sewer, drainage, gas, and telephone lines.  Barletta and our DB Team design members coordinated with the cities/towns, utility companies and various state and federal agencies to successfully complete this project on budget and on time.

As the Design-Build entity for the $31M MassDOT Hines Bridge replacement project, completed in July 2012, Barletta led a team of prominent design firms.  The Derek S. Hines Memorial Bridge carries Main Street over the Merrimack River, which is the major roadway that serves the nearby residences and businesses in Amesbury, Newburyport, and Salisbury.  The contract called for the complete design and replacement of the bridge, including the bridge substructure/superstructure and related roadway approaches.  The bridge is comprised of one steel framed swing span with one steel girder framed approach span at each end and totals 425 feet.  A complete electrical and mechanical system was designed and installed to operate the moveable portion of the bridge.  In order to close the bridge to traffic, an extensive traffic management plan was implemented which included the retiming of signals at 18 intersections along with detour signing and coordination with MassDOT and the Towns of Amesbury, Salisbury and Newburyport.  Sitework around the bridge consisted of rebuilding a granite block retaining wall into a cast in place concrete wall with granite facing and the rebuilding of a granite sea wall. The north and south approaches to the bridge were rebuilt along with sidewalks and traffic signals The Hines Bridge is located within a designated historic site; maintaining all existing features of the bridge to the greatest extent possible was important to the Amesbury Historical Commission (AHC), and our team worked to meet their strict requirements and preserve the historical integrity of the bridge structure within the new design.  This project required coordination with MassDOT’s Environmental Services Division and various applicable environmental agencies, including the US Army Corps of Engineers and the US Coast Guard.  Our DB Team members worked closely with the towns, historical commission and various state and federal agencies to successfully complete this project on budget and ahead of schedule.
