Next traffic pattern (modified phase II detour) begins April 30, 2018
Update for April 25, 2018
Modified phase II detours for the Castle Creek Bridge / Hallam Street Improvement Project will begin at approximately 7 a.m. on Monday, April 30. This is a change in the schedule; originally this shift was set to occur May 7. Mondays-Fridays and most Saturdays, from approximately 7 a.m. to 7 p.m. outbound motorist will use the Power Plant detour. Significant traffic delays are anticipated during peak travel times for both inbound and outbound traffic. These detours will be in effect until June 12 when crews will stop work before resuming with Phase III on approximately August 13.
“Project crews are tracking well with their overall construction schedule. Modifying the schedule and routes enables crews to begin installation of permanent roadway instead of using of temporary asphalt,” said project manager, Hailey Guglielmo. “As we transition into phase II we want to remind motorists to use the official detour route as the west end will be configured to prioritize the detour. That will be the most efficient way out of town besides taking advantage of public transit or riding your bike. The best way to stay informed on project schedule and detours is to sign up to receive project updates.”
Updates on construction activities, schedule, detour routes and alternative transit will be shared via the project update email. To sign up, reach out to the project hotline or click here.

Project Facts & Myths
Update for April 9, 2018
Project construction is underway on this critical connection for our city. All of us involved in the project – City of Aspen Engineering, Parks, Parking and Street department thank you for your patience. We acknowledge that construction projects are never ideal for our residents, businesses, and guests, but the end result will mean increased safety for all users, improved connectivity, and vital infrastructure upgrades that will help support the demands on this corridor for years to come.
Since we’ve heard some misinformation out there, we’d like to share some facts about the project.
Myth: This project is not important.
Fact: This is a top 10 accident spot for the city. This is the busiest corridor in Aspen for motorists, pedestrians, cyclists and bus users. This corridor has also been identified through public input in the Bicycle and Pedestrian Master Plan (2015) and the Parks and Open Space board as one of the top areas needing attention.
Below the work site is a network of underground utilities and infrastructure that hasn’t been touched in decades. The infrastructure is failing and has required several emergency repairs over the years. Emergency repairs are highly interruptive and costlier than making proactive repairs.
M: This is just a trail project.
Fact: In addition to completing this critical trail corridor, the project will make necessary repairs to failing infrastructure and utilities and improves safety for all users. Within the $4.65 million project budget, less than 15% of the total cost is for trail construction on the bridge and along Hallam Street. While the trail and transit infrastructure upgrades will be visible improvements to the area, the bulk of the project scope takes place underground.
M: This project will benefit only pedestrians and cyclists.
Fact: With roadway repairs, intersection improvements, dedicated bus queues and improved crosswalks – to name a few – there will be better sightlines for all users and will make motorist and transit travel smoother along the roadway. These and other improvements, like the railing separating pedestrians and bicyclists from vehicles on the bridge, also increases comfort and safety levels for all.
M: This project goes through the summer.
Fact: From June 12 to August 12 there will be no work that has traffic impacts. This stop in work was designed to provide a break for residents, businesses, and commuters during some of the peak season when Aspen sees some of its highest overall traffic counts for the year.
M: The project ignored a better option for a timeline/work schedule.
Fact: In this project plan, the contractor worked closely with the city developing a phasing plan that will maximize springtime work (when Aspen sees its lowest overall traffic counts). By maximizing work during phase I and II, we build in some flexibility for weather days, take a break from traffic impacts during the summer, minimize the number of work days during the peak summer season and steer away from winter working conditions.
This phasing plan also allows for crews to always keep at least one lane open across bridge, minimizing traffic impacts into town. By working extended hours, Monday through Friday and some Saturdays, 7 a.m. to 7 p.m., crews maximize daylight hours while minimizing noise impacts to area residents.
M: The Power Plant detour will be in effect for the entire project.
Fact: There are shifting traffic patterns for the duration of the project. From approximately April 6 to May 6, inbound traffic will take Hallam to 6th Street to Main. Outbound traffic will take 5th Street to Hallam Street/CO-82.
We’ll see the Power Plant detour again during the daytime in phase II (May 7-June 11) and phase III (August 13-October).
Please know that we have heard your concerns and we continue to encourage feedback. The project team is always open to input and questions. As this project moves forward, we will strive to share clear and timely updates and to make adjustments to our operations when possible.
With a project this size, it is easy for misinformation to spread. Please remember that the best, most accurate information is found on castlecreekbridge.com, via the project hotline (970-618-5379) and the project email updates. If you have a question or feedback, please reach out.
This information also appeared in the Aspen Times on Monday, April 9.
Next traffic pattern (phase I detour) begins April 6, 2018
Update for April 4, 2018
Project crews are able to mobilize the phase I detour beginning at approximately 7 a.m. on Friday, April 6. This is a change in the schedule (originally this shift was set to occur April 9). This traffic pattern will be in effect 24/7 for approximately the next month when phase II begins. Significant traffic delays are anticipated during peak travel times for both inbound and outbound traffic.

Outreach Launches for Castle Creek Bridge / Hallam Street Improvement Project
Update for February 14, 2018
Project construction is set to begin on Monday, April 2, 2018 with traffic and pedestrian detours. One lane is needed on both the bridge and Hallam Street for construction access and work. Sign up here for project news and updates emails.
Our team is working towards finalizing project details and measures to minimize impacts to residents and commuters. There will be delays, but we’re aiming to reach as many people as possible to increase project awareness, explain logistics and encourage self-preparation.
Construction to begin the project in 2018!
Update for June 19, 2017
The full project will be placed for bid in August of 2017. The anticipation for the start date pending Council approval would be in April of 2018. This would include the full span of the project beginning at the west end of Castle Creek Bridge and ending at 7th Street.
The improvements on Hallam Street between Castle Creek Bridge and 7th street were placed to bid in March of 2017. The City did not receive any qualifying bids at that time. The Living Lab Experiment could not be reconstructed due to the availability of qualified contractors and budget restrictions.
Living Lab Finalized Construction
Update for April 18, 2016
The Living Lab Experiment completed construction for the install and is scheduled to remain in place until July 29th.
The next step in the experiment will be to evaluate the amount of use on the trail and to evaluate the traffic conditions. All traffic patterns will be evaluated by a consultant and compared to the information that was gathered in 2015. This will allow the City to fully determine the impact on traffic.
Living Lab Construction Update
Update for April 12, 2016
Construction is anticipated to resume on Wednesday 4/13/16 if the weather cooperates. The trail is currently open.
The final joint between the new and existing sidewalk will be grouted for a smooth transition between the two. This will be the final measures for construction and will have less than a day of closure.
Living Lab Experiment
Update for May 24, 2016
Fox Tuttle Hernandez Transportation Group will begin to study traffic in a similar manner as the traffic study that was provided last summer. The two studies will be able to compare the impact the Living Lab Experiment has had on traffic patterns on the bridge.
2016 Living Lab Commonly Asked Questions
- Why is the project ending on July 29th instead of extending throughout the bike season?
A: The Living Lab Experiment has been approved through Council for three months. However, we believe the lab can extend into the fall if the public wishes this to extend. Staff will report to Council for a Work Session this coming summer on progress for the Living Lab Experiment. Public input could increase the length of the project if the project is successful and well received. Please let Staff know your thoughts on the project.
