Construction Project Status

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

The following projects are currently under construction:

• Exit 1 Ramps and Bridges - The $22.2M contract for construction of Exit 1 Ramps and Bridges was awarded to SPS New England, Inc. in August 2007. This project replaces seven structurally deficient bridges on the "RED LIST" and reconstructs the ramp approaches to all the bridges.
• Cross Street Bridge - a new bridge will be 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. R. S. Audley, Inc. of Bow, NH is the construction contractor.
• Exit 2 Park-and-Ride - The Exit 2 Park-and-Ride construction contract was awarded to Continental Paving in March 2007. Construction is underway and will continue through the 2007 construction season.
• Exit 5 Park-and-Ride - R.S. Audley, Inc. has been working at the Exit 5 Park-and-Ride site, which will provide 443 spaces, since February 2007. This contract also includes reconstruction of a portion of Rockingham Road and expansion of the Symmes Drive/Vista Ridge Drive intersection. The contract for construction of a bus maintenance facility and bus terminal was awarded to North Branch Construction in August 2007.
• Exit 5 Bus Terminal & Bus Maintenance Facility - This project includes construction of a bus terminal, bus maintenance and storage facilities, and adjacent site work allowing for 275 overflow parking spaces. The construction contract for the buildings and related site work was awarded to North Branch Construction, Inc, in August 2007.

Completed projects:

• Exit 4 Bus Terminal - The bus terminal at the Exit 4 Park-and-Ride opened to the public on May 14, 2007.

Projects to start soon:

• Exit 5 Ramps – Work under this Exit 5 contract (14633E) will create 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 will help improve the interchange capacity and improve safety on the mainline. This contract is expected to advertise in April, 2008.
• Exit 3 Southbound Off-Ramp – 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 is expected to advertise in May, 2008.
• Exit 3 Northbound Mainline – A new section of roadway will be constructed, relocating the northbound lanes closer to the existing southbound lanes. This construction will tie in the two new bridges constructed under the other Exit 3 contract and will allow shifting of traffic under future contracts. This contract is expected to advertise in August, 2008.
