Green completed several bridge designs and reviews under MassDOT’s Statewide Engineering Design and Review Services contract. One of the design projects that we were assigned under this contract was the replacement of Bridge S-03-005 carrying Clark Road Extension over the West Branch of the Farmington River in Sandisfield, MA.
The existing bridge, built in 1938, was a single-span two-girder bridge which had been deemed structurally deficient and functionally obsolete due to its condition and substandard bridge safety features and approach geometry. The challenge of this project was that we had a short duration in which the bridge could be built. With that in mind, we developed a temporary prefabricated pedestrian bridge, built to the north of the existing bridge and temporary parking on the east side of the river, that provides the homeowners and Town access to the properties while the proposed bridge was being constructed. We worked closely with MassDOT and the fabricators to develop non-standard railing details that met the desired crash-test level and laying out staging areas to ensure that the bridge could be assembled and erected at the site quickly.
