Castle Creek Bridge/Hallam St. Improvement Project – RFTA Impacts

Hotline (call or text): 970-618-5379


The Castle Creek Bridge/Hallam Street Improvement Project seeks to improve safety and function for pedestrians, cyclists and motorists on the busiest street in Aspen, CO. Key project components include: a protected 8-foot-wide concrete trail, upgraded bus shelters, repaired roadway and improved intersections at both Seventh and Eighth Street. These improvements will increase user safety, promote multi-modal connectivity, upgrade our public transportation infrastructure and enhance corridor aesthetics. A selection of project renderings is on page 2 or visit the project website. The project design has been a collaboration with many stakeholders including the City of Aspen Transportation, Streets, Engineering, Parks and Utilities. Colorado Department of Transportation and the Roaring Fork Transportation Authority have been critical stakeholders through the design of this project. Public and stakeholder outreach will continue to be a top priority for the duration of the project.

Castle Creek Bridge/Hallam Street Improvement Project construction begins on April 2, 2018 with an estimated completion date of October 2018. The project will be constructed in three primary phases with a no work period between phase II and phase III from June 12 to August 12 during peak season. Each work period will have traffic, bike and pedestrian detours. Significant traffic delays are anticipated during peak travel times for both inbound and outbound traffic.


RFTA bus service is FREE from the Brush Creek Intercept Lot through Aspen. There will be additional buses running between Rubey Park and the Brush Creek Intercept lot Monday-Friday during peak morning and evening commute hours beginning May 1st (see schedule to the right). These time points are in addition to RFTA regular service. Parking at all RFTA Park and Ride locations including the Intercept Lot and Buttermilk is FREE. Buses do not have to take the Power Plant detour and will be the fastest way to get around and out of town.

It is anticipated that the 8th Street stop will be closed for the duration of this project. Additional anticipated bus stop closures: 7th Street, 6th Street and 2nd Street (outbound).
