92-Year-Old W. 8th Ave Bridge to Get Major Reconstruction Over Platte

For nearly a century, the W. 8th Avenue Bridge has served as a fragile artery connecting the West Side to downtown, its decorative cement railings outlasting their structural purpose. Now, 17 distinct transportation notices filed on June 21, 2026, confirm the city is finally ready to tear down the 92-year-old viaduct and replace it with a modern crossing over the South Platte River.

This coordinated filing spree signals the start of a massive infrastructure overhaul for the 80211 ZIP code, targeting the most critical choke point for commuters, cyclists, and pedestrians in the region. The project moves beyond routine maintenance to a complete reconstruction of the bridge and the adjacent Alameda Avenue underpass, aiming to resolve decades of congestion and safety hazards.

The centerpiece of the overhaul is the W. 8th Avenue Bridge replacement. The original structure, which opened in 1937, has long exceeded its useful life and currently forces 22,500 vehicles daily through a single-lane configuration. The new design eliminates this bottleneck by adding a second eastbound through lane and carving out a dedicated 10-foot multi-use path for cyclists and walkers. This addition directly addresses the safety concerns that have plagued the corridor since the bridge's construction.

Simultaneously, the Alameda Avenue Underpass Replacement project advances to improve connectivity between Santa Fe Drive and Broadway. Records indicate the work focuses heavily on ADA compliance and active transportation, upgrading bike lanes and pedestrian paths to create a seamless link for commuters moving between the western neighborhoods and the downtown core.

While the specific applicant and construction timelines remain unconfirmed in the initial filings, the density of the 17 notices points to a synchronized push to unlock federal funding and meet reporting deadlines. The inclusion of the 16th Street Mall Plan Implementation in the same batch of records suggests city planners are viewing these western gateway projects as integral to the broader downtown circulation network.

Residents in the Highlands, LoHi, and Baker neighborhoods should prepare for significant disruptions as the design phase transitions into active construction. The city is expected to release updated traffic management plans soon, detailing lane closures and detour routes.
