This bridge replacement project located on Interstate 93 begins approximately 1,100 feet south of the Grandview Road overpass and extends north approximately 1.1 miles to just south of the Exit 12N. The project focuses on replacing the I-93 NB and I-93 SB Red Listed bridges over I-89 and the Turkey River, minor repairs to the Collector Distributor (CD) Road Bridge, resurfacing 1,650 feet of I-93, and reconstructing 4,050 feet of I-93. The project will also include replacing the median guardrail, replacing the existing drainage, work on I-89 to remove and reconstruct the bridges, work on the I-93 SB off ramp to I-89 NB, approach work on the I-93 NB off ramp, and rehabilitation work on the CD Road.

This project consists of converting the I-93 mainline cash and EZPass Toll Plaza in the Town of Hooksett to an Open Road Tolling facility. The project includes the widening and rehabilitation of the existing toll plaza, roadway widening and reconstruction, and bridge rehabilitation. More specifically, construction of four toll lanes, islands, booths (two in each direction), extended plaza canopy, demolition of six toll lanes, construction of four Open Road Toll lanes (two in each direction) and installation of full span toll gantry over the Open Road Tolling Lanes. There will also be ramp work and the construction of a new closed drainage system and three permanent storm water treatment basins. Bridge work includes deck replacement, deck rehabilitation and/or bridge rail replacement improvements along the I-93 bridges over Hackett Hill Road, Ramp A-B, and Cross Road. Gated ramps will be constructed at the southerly and northerly limits of the project providing maintenance and emergency access to/from I-93 at Cross Road and Pine Street.

This project will widen NH 107 from the westerly limits of the I-95 SB On/Off ramps east to the intersection with US 1 to accommodate the addition of two lanes. The NH 107 Bridge over I-95 will be widened 29’ on the south side with the curbing, guardrail and fencing to be replaced on the north side. The existing deck will be rehabilitated using full/partial depth deck repairs and include the placement of new pavement and membrane. The existing roadway pavement will be replaced and step box widening to accommodate the additional lanes on the approaches to the bridge. The I-95 NB Off Ramp will be widened to three lanes along its approach to NH 107 (dual left turn lanes with a right turn slip ramp). A new traffic signal will be placed at the I-95 SB Off intersection with signal alterations at the I-95 NB Off and US 1 intersections (the signals will be interconnected). A sidewalk will be constructed along NH 107 from Spur Road to the west, terminating just beyond the I-95 SB Off Ramp. All of the improvements are within the existing ROW.

This project involves reconstruction of the I-93 SB mainline, SB Ramps, and NH 111 Relocation at Exit 3 in Windham. Some of the construction elements include:

• Reconstruction and widening of the I-93 Southbound barrel, beginning approximately 2.20 miles south of Exit 3 and continuing northerly to approximately 1.20 miles north of Exit 3 (total length of approximately 3.5 miles).
• Construction of the I-93 southbound off-ramp to match to the previously constructed off ramp relocation.
• Reconstruction of the SB on-ramp (approx. 2,200 1.f.).
• Construction of NH 111 Relocation which includes over 1 mile of new off line construction.
• Reconstruction of the Wall Street approach to NH 111.
• Construction of an approach (connector) from the existing NH 111, to the relocated NH 111 at the Wall Street Intersection.
• Construction of approximately 1,100 1.f. of sound abatement wall along the I-93 southbound barrel, in the vicinity of May Lane and Jewell Drive.
• Construction of Water Quality Measures to include five (5) wet extended detention basins, two (2) gravel wetlands, one (1) treatment swale, and three (3) detention excavations.
• Construction of ITS conduit along the westerly side of the I-93 SB mainline, and along the NH 111 relocation, to support the intended I-93 future ITS infrastructure.
• The Wall Street and SB ramps traffic signals will be coordinated, and utilize fiber components. The proposed I-93 roadway work includes full reconstruction within majority of the work area and pavement overlay work at the northerly and southerly tie-ins. The proposed NH 111 Relocation work consists of complete off-line reconstruction, pavement rehab work, and interim work.
