The Denver Department of Transportation and Infrastructure (DOTI), in collaboration with Krische Construction, Inc. (KCI), have begun the replacement of life safety systems throughout the tunnel on the southbound lanes of Speer Blvd. located between Lincoln and Broadway.

The project will install a new tunnel specific fire alarm system, fire suppression system, and controls for the automated operation of the smoke evacuation system to improve safety in emergency situations. The most noticeable improvement will be the complete replacement of the lighting system in the tunnel with all new light fixtures and controls to better illuminate the tunnel during the day and night.

The Weir Gulch project is a key project in a high priority basin to reduce flood risk to the Sun Valley neighborhood, as well as a high need to increase ped/bike mobility, restore natural habitat, and increase recreation along Weir Gulch. This project is a partnership between Parks and Recreation, the MHFD, and DOTI Infrastructure.

The scope includes replacement of the existing culvert at Decatur with a bridge, and channel modifications along Weir Gulch from the South Platte River to Decatur Ave. The channel modifications will incorporate a multi-stage, stream channel and floodplain to appropriately convey the base-flow, bank full flow, and overbank flows, and promote a vibrant and sustainable riparian and wetland community that will be an aesthetic benefit to the surrounding neighborhood. The design will also incorporate redesign of the adjacent trail to increase mobility along the corridor.
