Detour for Glenwood bridge starts Monday

Project phase expected to last 95 days, also affects many popular rafting spots on Colorado

Area motorists with plans to travel to the Roaring Fork Valley in coming days and weeks should brace themselves for a major traffic detour that will hit the Glenwood Springs area starting Monday.

Work on replacing the Grand Avenue (Colorado Highway 82) Bridge across the Colorado River and Interstate 70 shifts to its highest-impact stage starting at 12:01 a.m. Monday morning when the existing bridge is permanently closed and its removal begins.

For what is expected to be a 95-day period, all Interstate 70 traffic heading to downtown Glenwood Springs or farther up the Roaring Fork Valley toward Aspen will be detoured through the Exit 114 interchange in west Glenwood Springs to Midland Avenue and a detour route through downtown. A largely identical detour route applies to Roaring Fork Valley traffic heading to I-70.

Highway 82 through much of Glenwood Springs also will be reduced to a single lane, and motorists should expect heavy traffic congestion in Glenwood Springs, especially during morning and evening commuter-traffic hours.

From Monday through Sunday, Aug. 20, the bridge deconstruction work also will require all nighttime I-70 traffic passing through Glenwood Springs to follow a short detour route. The detour will be from 8 p.m. to 6 a.m. and will incorporate the main Glenwood Springs interchange at Exit 116, Sixth Street, and access to and from I-70 via a temporary break in the highway barrier.

The project also is requiring a closure on recreational boating on the Colorado River in the area of the bridge work, starting Monday and continuing for about 10 days. During that time the upstream No Name, Shoshone and Grizzly Creek boat put-ins in Glenwood Canyon will be closed. More boating closures are expected starting in late August.

For people wanting to avoid the Midland Avenue detour, numerous alternative transportation options exist in the Glenwood Springs area and continuing farther up the Roaring Fork Valley, including bike routes, and bus service that’s free on the portion from Parachute to Glenwood Springs.
