City of Austin officials face a 2025 deadline to define the scope of several cap and stitch projects that could reshape traffic and neighborhoods across the city.
Explained: In a Dec. 4 update to the Austin Mobility Committee, city staff said the Texas Department of Transportation revised the I-35 Capital Express Central project timeline, delaying construction of city-funded elements by three years while moving up the deadline for additional funding commitments.
The impact: The shift forces Austin to commit millions of dollars when designs are only 30% complete, increasing financial risk, city staff said. City Council approved an advance funding agreement last May for up to $104 million to support three downtown caps and two northern stitches, with future payments to be spread over several years and larger “balloon payments” due during final construction.
Looking ahead: Community engagement continues on northern stitches aimed at reconnecting East and West Austin. Final stitch locations are expected to be selected by City Council by the end of 2025.
