Dover, NH

     Severino Trucking was awarded the largest construction project the State has put out to bid in May of 2016: The Newington/Dover Project. This project is the final phase of construction that will connect the Spaulding Turnpike from the Dover Toll to Exit 1 at the Pease Trade Port with a four-lane highway for both the North and Southbound lanes. The project involves not only the widening of the Spaulding Turnpike, but also the construction of a full access interchange at Exit 6; removal of the existing US Route 4 Bridge over the Spaulding Turnpike along with the construction of a new bridge, construction of a roundabout at the intersection of US Route 4/Spur Road/Boston Harbor Road; construction of 18,000 lf of sound walls; and City of Dover water and sewer relocations.

     The Dover/ Newington project is one of the most complex projects to date being that has 8 traffic phases and subsequent phases within those to complete the project. There are also new items to Severino that will need to be completed for the project: one being High Modulus Columns that will support footings on the new US Route 4 Bridge and the other bring micro tunneling for new water and sewer lines under the Turnpike.

     Along with the new items are the standard construction items that are very familiar to Severino Trucking, but will be done on a much larger scale. Some of these items include 210,00 cy of excavation, 231,000 cy of embankment-in-place, 250,000 cy of selects, 85,000 tons of pavement, 262,150 sf of wood panel sound walls, 31,000 lf of drainage pipe, 468 drainage structures, two sewer pump stations, 3,700 lf of sewer pipe, and 3,000 lf of water pipe.

This project was completed Spring 2021.


Londonderry, NH

     This project is a continuation of a multi-phase subdivision in Londonderry. In the remaining phases, it consists of 5,400 LF of roadway to be constructed with drainage, sewer, and water throughout the entire site. This job includes about 50,000 CY of ledge blasting, as well as 70,000 CY +/- of excavation and 60,000 CY +/- of embankment. Between the remaining two phases, Severino will also prepare 85 house lots to be ready for foundations. 

     Lorden Commons also includes an offsite waterline to be constructed along Old Derry Road to feed the proposed subdivision. This project began summer of 2019 and is scheduled to be completed fall 2020. 

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. 



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.


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. 


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)


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.
