Hatches Harbor Dike, Provincetown, MA Hatches Harbor Dike is located near the airport in Provincetown, Cape Cod, MA. The existing structure was an earthen dike lined with amour stone on both sides. The existing single 24-inch pipe allows tide water to pass through. The new structure is constructed of pre-casted concrete box culverts with four 4’x7’ openings and concrete wing walls. The size of each opening can be adjusted by opening or closing the vertical gates. The purpose of the adjustable gates is to allow a desirable amount of tide water to feed the salt march and also to protect the airport during heavy storms.  Date Completed: 1998

Cooks Dam Bridges (Main Street) over Mill River, Northampton, MA
This project involved rehabilitation to two bridge structures for the City of Northampton: a 66' concrete arch structure and a 29' span steel stringer bridge.  The steel stringer bridge was upgraded to HS-20 loading and thus eliminated the need to post the bridge for reduced loadings.  Areas of spalled and deteriorated concrete to the concrete arch structure and the substructure elements were repaved.  Provisions were included for support of a new 8" water main across the structures new metal bridge railings (Type G-3) were installed across the bridges and on the approaches.  The bridges are located within a historic mill site; therefore, particular attention was given to the aesthetic impact of the bridge reconstruction on the surrounding area.  Date Completed: 1996

Route 202 (Winchester Road) over B&M Railroad, Templeton, MA
This project involved complete replacement of a deficient bridge structure with a new 3 span continuous steel stringer bridge.  The depth of the proposed superstructure was minimized and the roadway profile raised to provide an increase of 3 additional feet of clearance over the railroad tracks (21'-0") to allow passage of "double stack" railroad cars.  The proposed superstructure consists of an 81'-6" main span with 52'-3" end spans.  The bridge is constructed of unpainted, high strength, weathering steel.  The bridge provides a 40'-0" wide roadway with one 7'-0" wide sidewalk.   Concrete barrier rails and safety screening, which meet the federal standards for crash testing were provided on both sides.

New drilled caisson piers were constructed adjacent to the existing piers in order to avoid impacts to train traffic and minimize need for sheeting.  The existing pier footings were retained for use in supporting crash walls in front of the proposed piers.  The caissons also provided necessary flexibility to carry the required seismic forces with both piers being "fixed" to the superstructure.  The abutment foundations are stub abutments supported on steel piles driven directly behind the existing concrete abutments.  The bridge was designed to be built in two stages with two lanes of traffic to be maintained throughout the construction period.  Temporary traffic signals were provided during stage I to provide an one-way reversible traffic flow across the structure.  Date Completed: 1997

Walworth Street over MBTA & Bay Colony Railroads, Boston, MA
