Rebuilding I93: Salem to Manchester (NHDOT) — Construction Project Status

Construction Project Status

As NHDOT moves ahead with the design of I-93 Improvements, the work is being broken into individual construction projects. Each of these projects will be awarded individually to construction firms, but all fit together to improve the entire corridor. DOT has evaluated the I-93 corridor and broken the work into individual projects based on logical divisions of work, providing a realistic sequence of events structured to give maximum benefit to the public as each of the individual projects is completed.

The following projects are currently under construction:

Exit 3 Southbound Off-Ramp & Northbound Bridges – To ultimately reconfigure Exit 3 to a diamond interchange, a new southbound off-ramp will be constructed, replacing the existing loop ramp. This new ramp, located north of NH Route 111, will help to improve the interchange capacity and improve safety on the mainline. Also, two new bridges to carry the relocated northbound mainline over NH Route 111 and 111A will be constructed. This contract was awarded to Middlesex Corporation of Littleton, MA on October 8, 2008 and is expected to take two years to complete.
Exit 3 Northbound Mainline – Contract 13933G was awarded to George R. Cairns & Sons, Inc. in May 2009. The $27.2M contract involves the construction of 9,775 LF of I-93 NB mainline, 4,450 LF of I-93 SB mainline, and interim crossovers (north and south ends) transitioning to the existing SB lanes in the Exit 3 area of Windham. The construction will match into the new I-93 NB bridges over NH Routes 111 and 111A being constructed under the 13933K contract. The project is scheduled for completion in November 2011.

Completed projects:

Exit 1 Ramps and Bridges - The $24M contract for construction of Exit 1 Ramps and Bridges was awarded to SPS New England, Inc. in August 2007. The project replaced seven structurally deficient bridges on the "RED LIST" and reconstructed the ramp approaches to all the bridges. This project was completed in November 2009.
Exit 4 Bus Terminal - The bus terminal at the improved Exit 4 Park-and-Ride opened to the public on May 14, 2007.
Cross Street Bridge - A new bridge was constructed to replace the existing bridge which, due to age and deteriorated condition, had been placed on the DOT's "RED LIST" establishing this as a priority project. The new bridge opened to traffic on August 21, 2008. R. S. Audley, Inc. of Bow, NH was the contractor.
Exit 2 Park-and-Ride and Bus Terminal - The 470-space Exit 2 Park-and-Ride construction contract was awarded to Continental Paving in March 2007. Expanded bus service operations began in November 2008.
Exit 5 Park-and-Ride - R.S. Audley, Inc. completed the 443-space Exit 5 Park-and-Ride in October 2008. This contract also included reconstruction of a portion of Rockingham Road and expansion of the Symmes Drive/Vista Ridge Drive intersection. The reconstructed Rockingham Road (NH Route 28) opened to traffic in September 2008.
Exit 5 Bus Terminal & Bus Maintenance Facility - This project included construction of a bus terminal, bus maintenance and storage facilities, and adjacent site work allowing for 275 overflow parking spaces for the adjacent park-and-ride. The terminal and maintenance facility were placed into use in October 2008. Expanded bus service operations began in November 2008. The construction contract for the buildings and related site work was awarded to North Branch Construction, Inc, in August 2007.
Exit 5 Ramps – Work under this Exit 5 contract (14633E) created a new northbound on-ramp and new southbound on and off-ramps. The existing northbound off-ramp will be replaced under a subsequent contract. The three new ramps represent improvements to the interchange capacity and safety on the mainline. This contract was awarded to Severino Construction, Inc. in June 2008 and was substantially completed in the fall of 2009. Landscaping and final cleanup will be completed in the spring of 2010.
