Project Background

In Summer 2021, it was observed during a field inspection that a hole had formed in the Four Mile Run Park Trail bridge deck. After a follow-up structural inspection, it was determined that the condition of the bridge was not suitable for use by people driving, biking, or walking. To ensure the safety of trail users, the bridge was closed in August 2021. 

Photos of the bridge are included below. Based on the latest inspection, the bridge condition is rated as “poor” due to structural deficiencies in the decking and beams. 

Staff continues to monitor the impacts of recent cost and schedule trends on City capital infrastructure projects. The City is realizing increases in the costs for design and construction caused by material, service, and labor cost increases. Additionally, supply chain and material issues are causing unanticipated delays. For additional information, read the Fiscal Year 2023 First Quarter Capital Projects Status Report provided to City Council on January 24, 2023.

Trail Closures and Detours

Two bicycle and pedestrian detours are established:

  1. Four Mile Run Wetland Trail (recommended for daytime use)
  2. Lighted on-street Detour (recommended for nighttime use) 

 Additionally, the segment of the Four Mile Run trail at the intersection of South Glebe Road and West Glebe Road is currently closed until Spring 2023, as part of an unrelated project, the West Glebe Road Bridge reconstruction. Trail users should stay on the upper trail next to South Glebe Road and South Four Mile Run for about 0.25 miles to reconnect with the trail. Signs will be posted to direct traffic.
