EXIT 4 I-293

Manchester, NH

This project began in October 2013 and consisted of replacing four red-listed bridges and rehabbing one. It also included the construction of 19,769 sf of MSE retaining walls; installation and construction of 44,750 sf of wood panel sound wall anchored by 174 drilled shafts; constructing a thrid lane for the south bound barrel; ramp reconstruction and pavement rehab; drainage BMP's and improvements; water line relocation; and median barrier construction. 

This project was completed in November of 2016.

MAIN STREET

Concord, NH

This tri-phase project consists of the revitalization, reconfiguration, and reconstruction of both North and South Main Street in downtown Concord   including new brick pavers, underground utility work, and granite tree wells. The bustling street was narrowed to make way for a wider, more accessible, pedestrian walkway which in turn made it necessary to relay drainage to pick up the runoff along the new curb line. The project also included the replacement of water services, hydrants, and fire services. 

This project began in the fall of 2014 and was completed November 2016.

EXIT 5 SALEM TO MANCHESTER

Londonderry, NH

The first phase of this NH DOT project consisted of moving the exiting southbound on and off-ramps and the northbound on-ramp. This allowed for the next phase, to widen the North and South bound barrels of I-93 to take place. This first phase presented a new challenge to Severino as it was the first attempt at H-Pile and timber lagging, and large panel MSE walls. 80,000 cy of ledge was blasted on the side of I-93 for the new southbound on-ramp, combined with 40,000 additional yards of import to complete southbound off-ramp embankment. 

The second phase four red-listed bridges were replaced and a half mile of Route 28 was reconstructed and widened. In addition to work Exit 5, a wetland mitigation at Exit 4 furnished the sand layer for the project. 1,000' of South Road was reconstructed and a new box culvert was installed to relieve flooding in the area. 

EXIT 15

Rochester, NH

Exit 15, Spaulding Turnpike - Construction of approximately 0.5 miles of new northbound and southbound mainline, including realignment of the existing Northbound and Southbound on and off-ramps. Work included the replacement and widening of four existing bridges; Route 11 over Route 16, Route 16 over the Cocheco River, Route 16 over the abandoned B&M railroad, and Route 16 over Chestnut Hill Road. Also, one new bridge was created for the southbound off-ramp over the Cocheco Backwater.

The new alignment required the relocation of the City of Rochester’s existing 10” force main and 20” water main that ran under Route 16. Drainage relocations required jacking a 48” RCP under Route 11. Route 11 was reconstructed and widened to double its previous width to accommodate the new on and off-ramps. The new mainline and ramps required over 400,000 CY of imported material for their construction. The bridges required 4.7 million pounds of steel and 12,000 CY of concrete.

 

Completion of the $28.8M project was in October of 2012.

Little Bay Bridge 2010 (91)

LITTLE BAY BRIDGE

Newington/Dover, NH

This joint venture project with Cianbro Corp involved the construction of a new bridge to carry two North and South bound lanes over the Little Bay as well as a new pedestrian bridge accessing the old General Sullivan Bridge. 2,300 lf of mainlines shifted exisiting lanes onto the new four lane bridge to allow for improvements in the next phase. 2,700 lf of Hilton Drive was reconstructed as well. Three MSE were constructed totaling 14,000 sf and ranging in height from 8' to 33'. Sound walls were constructed atop 700 lf of the MSE wall on the West side of mainline. 

 

To gain access to Little Bay Bridge was building a causeway 150 feet out into the bay from each shoreline using 20,000 cy of class B stone up to 20' below average water level and 10' above 75' wide. This was a challenge considering Little Bay has the strongest currents in the USA. 

Materials totals to complete this project included 24,000 cy of gravel for under pavement, 12,700 ton of asphalt, 65,000 cy of common excavation, 45,000 cy of fill place, 12,000 sy of invasive species control, 7,000 lf of drainage pipe, 122 concrete drainage structures, two large storm water leeching galleries (BMP's), 5,700 lf of granite curbing, demo and abatement of three existing buildings, along with hundreds of other incidental items. 

LORDEN COMMONS 

Londonderry, NH

Lorden Commons was a multi-phase residential subdivision road off Old Derry Road in Londonderry, NH. The first phase consisted of 51 house lots, 3,500 feet of paved subdivision road with a closed drainage system and seven detention ponds to maintain storm water quality. A sewer system was constructed and connected to the Town of Londonderry's municipal sewer system. To complete this portion of the work, a half mile of cross country sewer main was installed through property to the Liberty Drive area off Route 28. All lots are serviced by underground power, telephone and CATV connections. To complete utilities, a 35,000 gallon fire cistern was installed in order to provide proper fire protection to homes that were constructed on the project.
