Previously studies from other transportation agencies have shown that using recycled pavement can reduce greenhouse gas (GHG) emissions as well as costs, the report says. VDOT officials say that using recycled materials on the project’s second phase will save $10 million and reuse 180,000 tons of material.
The report says the expansion project widens the interstate to six lanes with one travel lane and one shoulder lane being added. The project spans three localities and 21 miles. The project began in September 2015 and is designed to increase interstate capacity. According to the report, the project will also bring portions of the highway up to design standards, provide more evacuation lanes and reduce congestion.
VDOT says it is also upgrading drainage systems by adding larger, new pipes and installing additional stormwater management facilities. The stormwater management facilities are designed to control potential erosion and provide a measure of water quality treatment, the report says.
Future phases of the project include more construction and drainage work, the report says, along with a wider highway stretch past Williamsburg that should be completed by 2022.
