Progress to date and extended work hours:
Excavation of Sanderson Gulch in order to prepare for the installation of large capacity, underground box culverts, is underway. Heavy equipment and crews will be working on the gulch between Sanderson Gulch Park and S. Platte River Drive. In order to meet schedule deadlines, construction crews will begin working extended hours. Work crews and heavy machinery will operate between 6 a.m. and 10 p.m., six days a week, Monday through Saturday. Noise levels are being monitored. Please see the notice of extended work hours for further details:
Detours and bicycle safety:
Two City of Denver infrastructure projects are occurring at the same time and geographically close to one another: the Sanderson Gulch storm water project and the Mississippi Avenue Bridge rehabilitation project. The South Platte River Trail is closed to pedestrians and cyclists where it passes under the Mississippi Avenue Bridge. Cyclists are urged to use the designated detour onto Huron Street in order to get back onto the bike trail. It is not safe for bicycles to be on S. Platte River Drive which is an active construction site, or on Lipan Street which has heavier than normal traffic due to a related construction detour.
Traffic detours and delays continue on both the west and east sides of the Sanderson Gulch project site.
S. Platte River Drive:
S. Platte River Drive is closed in both directions from S. Santa Fe Drive to W. Florida Avenue. Northbound traffic on S. Platte River Drive will continue to be detoured onto W. Florida Avenue and north on S. Lipan Street. Through traffic on southbound S. Platte River Drive will be detoured onto S. Huron Street.
S. Huron Street, S. Inca Street, and S. Jason Street will remain open to business traffic at W. Louisiana Avenue, but will have no access to S. Platte River Drive.
S. Lipan Street and W. Arkansas Avenue:
S. Lipan Street remains open in both directions, but traffic lanes will be shifted to the west away from the active construction zone. Flaggers will help direct traffic. There will be no access to S. Lipan Street from W. Arkansas Avenue. W. Arkansas Avenue will be closed for one block between S. Mariposa Street and S. Lipan Street.
Cyclists can rejoin the South Platte River bike trail at the intersection of S. Huron St. and S. Platte River Drive. Please follow the orange detour signs. Cyclists may not enter S. Platte River Drive, it is closed.
The Sanderson Gulch construction project between S. Lipan Street and S. Platte River Drive will reduce flood risk to nearby properties, improve water quality flowing into the South Platte River and create a more pleasant public area for the community to enjoy.
The project involves installing larger storm drainage pipes to provide greater protection during bigger storm events, and improving the naturalized channel to manage and clean water during smaller storm events. The project will take approximately 12 months to complete.Questions? CCD.firstname.lastname@example.org
