Changes to the intersection that joins Highway 101 with State Route 6 in Raymond begin next week, according to the State Department of Transportation.

On Monday, Rognlin’s Inc. will begin construction work on the 101/State Route 6 intersection improvements and drainage work project that will add a roundabout in this location.

“Due to its age and the corrosion from the salt in the air, the signal requires frequent maintenance, which takes extra time and money,” said project engineer Colin Newell. “By removing the signal and installing a roundabout, we’re lowering the long-term operational and maintenance costs, and improving safety and traffic flow through the intersection.”

In addition to building the roundabout, this project replaces a failing drainage system with a new system between Heath and Duryea streets and adds new sidewalks to the west side 101 in the same area.

Contractor crews are scheduled to work Monday through Friday, from 6 a.m. to 6 p.m. Travelers should expect daytime delays of up to 20 minutes through the work zone, with flaggers directing alternating, single-lane traffic. Once crews remove the signal and begin construction of the roundabout, travelers will be routed through the work zone — around the clock — by flaggers. This project is scheduled for completion this fall.
