Beginning mid-day Monday, July 25, motorists at the Town Center interchange in Vail will be directed into a new lane configuration that will add additional capacity for commuters accessing the Interstate 70 westbound on-ramp. The northbound lane beneath I-70 will be restriped to carry two 11 foot lanes of traffic through the underpass around the north side teardrop roundabout, and then onto the I-70 westbound on-ramp.
