Project Description

The City of Englewood has awarded a construction contract to Jalisco International to widen and rehabilitate the Dartmouth Avenue bridge over the South Platte River. The bridge will be widened approximately fifteen feet to accommodate an additional drive lane and include a new five foot wide sidewalk on the south side. Roadway surface improvements will include an asphalt mill and overlay of Dartmouth Avenue from Santa Fe to S Platte River Drive. Intersection improvements including new traffic signals will be completed on both sides of the widened bridge. Construction phasing will be utilized to keep two lanes of traffic open during the life of the project. Phase 1 will have two lanes of traffic open on the south side of the bridge while the north side of the bridge deck is replaced. Phase 2 will open one lane of traffic on the north side of the bridge and one lane of traffic on the south side of the bridge while the middle of the bridge deck is replaced. The final phases will have traffic on the north side of the bridge while the south side of the bridge deck is replaced, and the structure is widened.

Timeline

The Dartmouth Bridge project has been delayed due to 3rd party construction delays related to the project. Currently, contractors are focused on finishing the substructure units on the south side of the bridge. Once this phase is complete, the installation of girders and the final stages involving the deck, sidewalk, and rail can proceed. Delays stemming from third-party utilities have extended the anticipated project completion date from summer 2024 to winter 2025.
