The Castle Creek Bridge detour route is shown in this map.


Due to weather forecasts calling for cold temperatures and snow on Thursday, the remaining work activities for repairs on the Castle Creek Bridge have been rescheduled for Monday and Tuesday of next week. 

The Power Plant Road detour, which started on Monday, was scheduled to remain in place through the week. It continued through Tuesday evening and will now resume on Oct. 14 and 15. Traffic patterns will resume as normal for the remainder of this week. 

Crews on Tuesday were wrapping up the placement of new asphalt across the bridge. Remaining activities include concrete work and work at the bridge joints.

When the detours return next week, they will take place from approximately 7 a.m. to 7 p.m. each day. Westbound (down valley) traffic on the Castle Creek Bridge will be detoured via Sixth Street to Power Plant Road. Eastbound (up valley) traffic will continue to use Castle Creek Bridge with intermittent holds for outbound buses. Please plan extra travel time as significant delays are anticipated.

 Follow flagger instructions and signage. Schedule is weather dependent and subject to change.

 Roaring Fork Transportation Authority (RFTA) buses and school buses will be exempted from the detour and will be staged on Seventh Street. At intermittent times, traffic control will stop inbound traffic to allow for the buses to cross the bridge. Commuters are encouraged to ride RFTA as the bus has priority through the roundabout and will not have to use the Power Plant detour.

 The Eighth Street bus stops will remain open during this work. The Sixth Street bus stop will be closed. Riders should use the Fourth Street bus stop. Street parking along the detour route (Sixth Street and Smuggler Road) will be temporarily closed during detour operations. 

Updates will be announced via travel advisory and the City of Aspen’s Road Closures and Construction NotifyMe email and text alerts. Sign up for notifications at For more information on this work, please contact the project team at 970-924-0620 or
