Nearly $90M investment needed to address Austin’s aging bridges, city reports

The Austin Transportation and Public Works Department (TPW) has identified dozens of bridges in imminent need of repair, rehabilitation or replacement. The city will need to invest $89.5 million over the next five years to prevent closures and avoid load restrictions, according to a recent State of Austin Bridges report published by the department. 

Out of the approximately three dozen bridges noted as being at the end of their useful life expectancy in the report, the city will need to replace two major bridges and repair seven others. Major bridges are any structure with a span greater than 20 feet. Currently, there are 164 major structures that have lived passed their anticipated 50-year design life, despite the majority remaining in good condition. 

Additional rehabilitation and replacement will be required for another 26 smaller structures. These include bridges with 20 feet or less, culverts, pipes and those designed for pedestrians and bicyclists. 

While the $89.5 million will cover the highest priority work, the report stipulates that the city will need to tack on another $30 million in capital funding annually to maintain the bridge network. The TPW has set two goals to achieve through dedicated capital investments. The first will to get all bridges rated as structurally fair or in better condition. The city must also work to ensure 90% of major bridges and 80% of smaller bridge and pedestrian and bicycle bridge structures obtain a satisfactory or better rating. 

As of the report’s release, Austin’s bridge infrastructure remains in immediate good standing. The city has 94% of 466 major bridges in satisfactory or better conditions, requiring a $66 million investment to remain in adequate standing over the next five years. Another 97% of the city’s 840 small bridges and culverts are in similar condition, only needing $16.5 million. Finally, 60% of the 20 pedestrian and bicyclist bridges are in comparable shape, requiring a $7 million investment over the same time span. 

The major bridge rehabilitation and replacement projects take priority in the TPW’s report. These projects include: 

• Replacing Barton Springs Road Bridge over Barton Creek – $20 million. 
• Rehabilitating Slaughter Lane Bridge over Union Pacific Railroad (UPRR) – $16 million. 
• Replacing Delwau Lane Bridge over Boggy Creek – $14 million. 
• Rehabilitating William Cannon Drive Bridge over UPRR – $8 million. 
• Rehabilitating East 7th Street at Tillery and CAPMETRO RR – $5 million. 
• Stabilizing the bank at the River Plantation Drive Bridge over Onion Creek – $3 million. 
• Rehabilitating Redbud Trail Bridge No. 1 and No. 2 over Colorado River – no estimate given. 

However, despite the need to maintain bridge infrastructure, the city is facing financial issues that may stump development. Austin faces a budget deficit evident in its five-year financial forecast, projecting a $26.4 million shortfall for 2027. The deficit is only expected to get worse, which may force the city to compromise with millions of cuts to other critical sectors, including housing, education and job programs. 

The city will likely need to turn to bonds and grants to acquire the capital needed to follow through on the TPW’s vision. However, city officials are concerned about overstepping bond programs following years of hiked tax rates and voter-approved investments in homelessness services, parks and public safety. While bonds are dependable and effective, the city may have to rely on federal grants to advance these initiatives.
