Purpose
The purpose of the Union Avenue Bridge Rehabilitation is to repair the deteriorating bridge deck, which will create a smoother riding surface across the bridge. The most recent bridge inspection report noted a deteriorating bridge deck that needs replacement. A new bridge deck will create a smoother riding surface for trucks and commuter vehicles to traverse the South Platte River along Union Avenue. A new sidewalk and Greenway Trail connections will be installed to improve connectivity to Centennial Park.
Project Description
This project will be completed in two phases. The first phase will be a life cycle cost analysis (LCCA) to determine the best course of action for design and construction. The LCCA is a critical part of this project which will determine the actual cost of a design option over its entire lifespan including construction costs, maintenance and operational costs, and overall operational lifespan. The LCCA will ensure we are designing and building the best option for this location and that the money we spend on this project will go the furthest. LCCA is also an essential tool to apply for and receive federal funding. After the LCCA is completed and federal funding is explored, the most economical design will then be completed, and construction will begin shortly after.
Schedule
The LCCA was completed in the fall of 2024 and the consultant began the final design phase of this project in early 2025. The city has received the 30% design plans, which are currently under review. In addition, the project team is preparing draft grant applications for review by the city and the State of Colorado.
Construction Impacts
Traffic control options will be explored during the design phase of this project, but it is very likely the bridge will need to closed to traffic for the duration of construction. The bridge is narrow and leaving one lane open during construction will increase the time needed to complete construction and be dangerous for the construction workers given the constraints of the working space.
A detour down to Belleview or up to Oxford will likely be explored and only add minutes to a commute typically using Union.

The city applied for a Bridge and Railroad (BRO) Grant to help fund the rehabilitation of the Union Avenue Bridge. While the application was not selected for funding during this grant cycle, the project remains a priority.
To keep the project moving forward, city staff is working with the design consultant to divide the project into two phases.
Phase 1: Replace the deteriorating bridge deck using local funding. This work will address the bridge's most immediate maintenance needs and provide a smoother driving surface.
Phase 2: Widen and rehabilitate the bridge, including planned pedestrian and trail improvements, when grant funding becomes available.
City staff anticipates receiving the revised phased design plans in late summer 2026. Additional project updates and anticipated construction timelines will be shared as the project advances.

The city has received a proposal from the design engineer to design the bridge improvement, which includes a widening option that will be pursued if grant opportunities can be realized. This proposal is being negotiated with the consultant and will be sent to city council for approval in late 2024.

The life cycle cost analysis (LCCA) has been completed, and staff is currently evaluating the most effective course of action. The team is reviewing the LCCA to identify the alternative that will optimize Englewood's financial resources while also enhancing our prospects for securing external funding.
