West 8th Street Closures
Consultation has concluded
Update 4/27/2020:
Crews are pulling the temporary scaffold bridge today, and instead the construction fence and delineators have been moved to provide a route for pedestrians on the permanent sidewalk.
A person will be out directing pedestrians throughout the day. A temporary asphalt patch is planned for later today and crews will then relocate the fence as shown below.
Update 3/24/2020:
The temporary trail crossing over the Church Ditch and connection to 8th Street will be a little challenging this week because the crossing area has been tightened for utility work. You will need to use the 8th Street West parking lot to connect to 8th Street and the trail for about a week. We recommend that riders dismount and walk through the area during this time.
-----------------------------------------------------
Recently, the Church Ditch and the Basecamp development at the end of 8th Street coordinated construction efforts to replace failing or under-capacity infrastructure. The developer’s part of the construction involves the replacement and installation of public utilities, including new water and wastewater mains. These improvements will serve both the Basecamp development and the Jefferson County Peaks to Plains trail head facility along Clear Creek Trail. The replacement and installation of the public water and wastewater mains will be paid for by the development in accordance with City codes and standards. The Church Ditch Company is replacing the culvert beneath 8th Street within the ditch Rights of Way. The culvert replacement is the component of these coordinated projects that requires the full closure of 8th Street, as well as the adjacent trail. The culvert replacement was initiated by the Church Ditch Company and coordinated with the development to minimize the impact to 8th Street and the trail. The work was scheduled in the winter months when trail use is lower than other times to further minimize the inconvenience. This work will also include enhancements to the trail crossing at 8th Street in the form of a raised crosswalk and improved sight distance for trail users and 8th Street motorists at the crossing. To be clear, the City is not allowing a closure for the convenience of the Basecamp developers. The City is holding the developers responsible for the public infrastructure improvements necessary for the construction of their project. When complete, the infrastructure will be turned over to the City. The closure is necessary due to the separate project by the Church Ditch Company.
City staff investigated alternative routes to keep a temporary trail open during this time, but they did not find any that seemed feasible, affordable, or safe. Since then, more research is being done to find a temporary solution. Meantime, signage has been added. Signage has been added to inform trail users of the closure and advise of alternate routes. The main alternative route is Washington Avenue. Signs have been added to New Loveland Mine Park, the pedestrian bridge over HWY 93, Iowa Street and Rubey Drive, 8th Street, and the Clear Creek Trail.
The duration of the closure is anticipated to be 8 weeks with an original target date of March 17 (since revised to April 1 due to weather) for reopening of the trail. This may seem like a long time, but the project requires excavation and removal of the old culverts and grading to the proper level. This is followed by forming and tying steel rebar for three different sequential concrete pours. Each pour is followed by a minimum of seven days or longer to get required concrete strength. Finally, the area around the box culvert is backfilled to the street and trail level.
City staff will continue to work with the contractor to shorten that duration in any reasonable way. As is standard with such construction, adverse weather or unforeseen issues could lengthen the construction schedule.
