Project Location: Beginning on US-5 in the Town of Hartford, at mile marker 0.000 (at the town line of Hartland/Hartford) and extending east for 2.810 miles and ending at mile marker 2.810 (at the intersection of the on ramps for I-91 South and I-89). The project then starts back up on US-5 at mile marker 3.875 (at the intersection of N Main St/Hartford Ave.) and extends northerly for 0.875 miles and ending at mile marker 4.750 (just north of the Devin Street).

Project Description: Work in the southern section of this project will remove the underlying concrete slabs. This process involves removing the pavement, then excavating the existing slabs. Once the slabs have been removed, new subbase will be placed in the void space followed by paving with an engineered pavement thickness. Due to the invasiveness of this process, it is anticipated that culverts will be replaced as needed, and new underdrain will be installed to promote drainage from the roadway. Guardrail will be evaluated for length of need and condition and will be replaced with new infrastructure.

In the northern section, work will consist of coarse-milling the existing pavement to a 2-1/4” depth, then placing a 1/2” lift of Type IVS pavement to level the road surface, followed but a 1-3/4” lift of Type IIIS pavement as the final wearing surface. Additionally, some guardrail work will be performed to repair and replaced damaged sections to bring full runs into compliance with the current standards. Shoulder berms that have built up will be removed to facilitate better drainage from the road surface, and some ditching work may be performed to further aid in drainage.

The corridor will be evaluated for the installation of Centerline Rumble Strips (CLRS). CLRS will be installed where the speed limit is 45 MPH or greater, the pavement width is 14 feet in both directions, and the traffic volume exceeds 1500 vehicles per day. The CLRS will be stopped at Town Highway intersections, and anywhere that a residence falls within 100 feet of centerline. In these cases, the CLRS will be stopped and resumed 100 feet from either corner of the residence.

Note that this project is part of a composite contract with the Hartford NH PS24(3) project which will be paving the National Highway System (NHS) portion of US Route 5 and Hartford NHG SGNL(60) signal project at N. Main Street and Hartford Avenue.
