CEI was engaged to provide construction inspection support as part of the project inspection team for the Connecticut DOT. The I-84 Waterbury Project involved the widening (addition of a third travel lane and full width shoulders in each direction) and safety improvements to a 4.3 Km (2.7 miles) segment of Interstate 84 from Washington Street, east to Pierpont Road in the City of Waterbury. Included in this project was the realignment of the interstate roadway in the vicinity of Harpers Ferry Road (Interchange No. 24) to eliminate the existing substandard “S” curve alignment; interchange ramp reconfiguration; State and local road construction; and the relocation of the Mad River and Beaver Pond Brook.
As a result of the realignment of I-84 and the reconfiguration of the ramps, portions of the following State and local roads with intersections were reconstructed:
- Hamilton Avenue
- Harpers Ferry Road
- Scott Road
- Plank Road
- Reidville Drive
- Plank Road East
- East Main Street
The project also included the construction / replacement of 8 highway bridges (4 over watercourses), one pedestrian crossing over the Mad River, 7 culverts (5 within the Beaver Pond Brook, 1 within East Mountain Brook, and 1 within the Mad River), and 20 retaining walls.
The project also included replacing and upgrading traffic signals, new highway illumination, new signs and pavement markings, and replacing or relocating sanitary sewer, potable water and other public utilities.
Also included in the project was the rehabilitation of five existing culverts constructed with corrugated metal pipe (CMP). Of particular interest may be the use of innovative technology in the lining of the existing deteriorated CMP cross culverts located under high highway embankments. Among them are 750 mm (30 inch) and 1,500 mm (60 inch) CMP culverts located outside of the above identified project limits in the Town of Cheshire approximately 1,400 meters, (or approximately 4,600 feet) and 3,300 meters (approximately 10,800 feet) east of Pierpont Road respectively.
