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
Traffic detours and delays continue on both the west and east sides of the Sanderson Gulch project site.

S. Platte River Drive:
There will be increased drilling and construction activity on 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.  PLEASE SLOW DOWN and be aware of workers in the area.
