Northwest Groveland Drive to Helvetia Road

Washington County, Oregon

This project constructed a new two lane roadway that realigned Groveland Drive starting east of Groveland Road and re-connecting to Helvetia Road at the current intersection with Schaaf Road. Project will route stormwater runoff through a water quality swale prior to discharging off the site. The project also replaced the existing bridge with an 15 ft x 8 ft Aluminum Arch culvert on Helvetia Road at Waible Creek. The replacement of the culvert was unique in that we prebuilt sections in the project staging area and then carried them in with a loader and it was backfilled with a low density Cellular concrete. Key items of work included  9,250 SY of Cement Treated base 14 inches in depth, 625 cy of low density cellular concrete, 300 ft of 15 ftx8ft Aluminum Culvert, 2,900 Tons of HMAC.
