VAIL VALLEY, Colorado — The Vail Valley's four newest roundabouts are now being built with federal stimulus funds on either side of the Interstate 70 interchange in Edwards.

A pair of two-lane roundabouts will be built on the north side of I-70 at the intersection of Berry Creek and Beard Creek roads. Two more will be built on the south side of the interchange at the intersection of Miller Ranch Road and the Edwards Access Road.

The roundabouts are designed to improve traffic flow and safety at this interchange, which now has traffic lights. Additional improvements at the interchange include a bike path and drainage upgrades.

The contractor, American Civil Constructors, Inc., began the $6.4 million project on Monday and expected to finish by mid- to late-November.

Throughout the duration of the project, motorists will encounter periodic single-lane reductions on the Edwards Access Road and Miller Ranch Road but no manned traffic control during the peak hours of 7 a.m. to 9 a.m. and 4 p.m. to 7 p.m., Monday through Friday. There may be periodic single-lane closures on I-70, but there will be no impacts to I-70 travel over the weekends. While the Edwards rest area will remain open during construction, trucking companies may consider alternate sites for the next nine months.

“For several years, CDOT has worked closely with Eagle County to prepare ‘shovel-ready' plans to improve the interstate at the Edwards Interchange,” CDOT Resident Engineer Martha Miller said. “When funds became available, this project was identified as a high priority.”
