Location: Canton - Dedham - Milton - Randolph - Westwood Pavement and Bridge Preservation on I-95 and I-93 SCOPE OF WORK This project consists of resurfacing I-495 in Westford. The Southern limit is at the pavement joint located about 150 feet north of the bridge (W-26-019) over Boston Road (Mile Marker 83.33). The Northern limit of the project is at the pavement joints located at about 50 FT north of the Westford / Chelmsford Town Line on I-495 SB (Mile Marker 85.02) and at about 800 FT north of the Westford/Chelmsford Town Line on I-495 NB (Mile Marker 85.18). The total length of this project is approximately 1.85 miles. The limits of work include the ramps to/from Boston Road. The work to be done primarily consists of replacing the existing OGFC with UTBO (Ultra-Thin Bonded Overlay). The mainline shall be milled 1 inch to remove the existing OGFC and paved with 0.75 inches of UTBO-P (Ultra-Thin Bonded Overlay - Polymer Modified). The ramps shall be milled 2 inches and paved with 2 inches of Superpave Surface Course - 12.5 - Polymer. The proposed paving shall meet the existing pavement at ramps/bridges/project limits through 75 ft paving transitions from 0.75 inches to 1 inch. The bridge decks and buffers over Tadmuck Road shall only be crack-sealed. Recessed pavement markings, preformed tape, and reflectors shall be installed throughout the project. Related work includes clearing; adjusting and rebuilding drainage structures; replacing damaged frames and grates/covers within the traveled way with locking frames and grates/covers; cleaning out drainage structures, drainage piping, and drainage outfalls and replacing Pedestrian Curb Ramps and Crosswalks within the project limits. This project is proposed to occur within the buffer zones of natural watercourses and bordering vegetated wetlands. Prior to construction, sediment control barriers will be installed to protect and prevent encroachment into environmentally sensitive areas.
