Full Closure of 72nd Avenue at Indiana Street

Arvada, CO – Starting at 11 a.m. on Sept. 24, W. 72nd Ave. for approximately 500 feet WEST of Indiana St. (Colorado Highway 72) will be closed for up to three months for a full bridge replacement. LOCAL access only will be permitted on 72nd Avenue between Quaker and Indiana Streets. View detour map.

During the closure to the west, the existing bridge over Croke Canal will be demolished and replaced with a box culvert designed to accommodate additional travel lanes. While a complete road closure was not initially planned as part of the project, due to conflicts with utilities and the adjacent irrigation canal a modification to the original bridge design was required. The full closure is necessary to complete work before water is conveyed through the canal.

The project is weather-dependent and the schedule is subject to change.  Updated closure information will be provided via message boards along the corridor, the project website ( and the project hotline 720-900-8670.

Expect traffic shifts on Indiana St.

Traffic shifts and narrowed lanes are anticipated on Indiana Street for several months. Motorists should continue to expect intermittent lane closures with alternating traffic on Indiana Street, from 8:30 a.m. to 3:30 p.m. (Monday – Saturday) during the full closure of W. 72nd Ave. One lane in each direction will be provided when work is not occurring and whenever possible during working hours.
