San Antonio’s US Highway 90 West Expansion Project, with a $500 million investment from TxDOT, is set to start in late 2025. The initiative expands the highway to six lanes, improving traffic capacity significantly amidst a 70% increase in traffic over the last decade. The first phase, costing $161 million, aims to last four years, focusing on widening the highway and constructing flyover ramps. Completion of this project is essential to accommodate the growing residential areas and expected doubling of daily vehicle count in the next 20 years.
San Antonio—The US Highway 90 West Expansion Project is set to commence in late 2025 with a total investment of $500 million from the Texas Department of Transportation (TxDOT). This ambitious initiative aims to expand US Highway 90 to six lanes and enhance connectivity for the growing traffic in the region, particularly between Loop 410 and State Highway 211 in west Bexar County.
Construction will begin in late 2025; however, the specific starting date is yet to be determined. This first phase of the project, which is fully funded at an estimated cost of $161 million, is anticipated to last approximately four years. It will focus on widening US Highway 90 and improving access roads, which will include the construction of flyover ramps linking US 90 and Loop 1604.
The expansion is especially crucial as traffic volumes on this section of US 90 have surged by over 70% in the last decade. Current projections estimate that the daily vehicle count on US 90 will more than double over the next 20 years, increasing from 70,000 to a staggering 150,000 vehicles per day. With these changes, the project is expected to significantly reduce future travel times by as much as 90%.
Following the completion of the first phase, the second phase of the project will focus on extending US 90 from Loop 1604 to State Highway 211, increasing the number of lanes from four to six. Phase two is projected to start in 2028 and is expected to take until 2032 to complete. The estimated cost for this phase is approximately $339 million, though it is only partially funded at this time. Electronic toll collection systems are also being considered for future operations across the newly expanded roadways.
As the far West Side of San Antonio has experienced substantial residential growth over the last 20 years, with multiple subdivisions developed in the area, the need for better infrastructure has become apparent. The existing roads have struggled to accommodate the rising population and the associated increase in vehicular traffic. The expansion of US Highway 90 is a proactive measure to manage this challenge effectively.
The current expansion project will be executed in multiple phases, with some timelines for future phases remaining unclear. In addition to traffic improvements, the project aims to enhance the overall infrastructure in the region to better serve the community. The construction of flyover ramps is tentatively slated for completion around 2034, subject to changes in funding and scheduling.
All project dates and financial estimates are subject to revision, depending on various factors, including construction conditions and funding allocations. The TxDOT emphasizes the importance of this project in addressing the traffic challenges and improving the infrastructure to accommodate the growing population in the area.
In summary, the expansion of US Highway 90 represents a critical investment in the future of transportation in San Antonio, aimed at alleviating congestion and improving connectivity for residents and commuters alike.
