About this project
Summary of work
I-90 is an important national east-west transportation route that connects many population centers in the U.S. In the Austin area, I-90 was built in the 1950s and the structures are at the end of their useful design life.
There are six sites along I-90 in Austin that have bridges that are scheduled to be replaced or repaired in 2023 to 2025. A bridge at 11th Dr. NE was replaced in 2017 and a bridge at 28th St. NE was replaced in 2022.

Upcoming public meeting
Outreach efforts to communities within Austin have been occurring since 2016 for the bridges. Another public engagement session is planned for summertime 2022 to discuss the latest designs, gather feedback and provide information. Sign up for email/text message updates to stay updated and informed.
What is the project timeline?
Which bridges are part of this project?
There are six bridges along I-90 in Austin involved in the project with each having different needs.
Oakland Ave. W / Hwy 105
A new bridge will be constructed at Oakland Ave. (Hwy 105) over I-90. Hwy 105 will be closed during construction. A detour will be provided using 14th St. The new bridge will include for a wide walkway, which will connect to a future city/county trail. This construction is currently scheduled for 2023. View the proposed design.
14th St. / Hwy 218 North
The two bridges at this location will be replaced by one bridge and roundabouts will be constructed at each ramp intersection with 14th St. Traffic will stay open to the extent possible during construction. Short duration detours will be provided at 4th St. This construction is currently scheduled for 2025. View the proposed design.
4th St. / Co. Rd. 45
A new interchange will be constructed to replace the current interchange. The new layout will provide for safer walkway crossings of I-90 and improved traffic flow. 4th St. will be closed for construction during most of 2024. 14th St. will be used as the detour route. This construction is currently scheduled for 2023-2024. View the proposed design.
Both I-90 bridges over 6th St. will be re-decked in 2024 along with the construction of two new highway bridges over the Cedar River. 6th St. under I-90 will remain open during this construction. This construction is currently scheduled for 2023-2024.
21st St. / Hwy 218 South
The 21st St. bridge and the south ramps will be reconstructed. The new bridge crossing will provide a wide walkway and connections to local trails. 21st St. will be closed during construction. 11th Dr. and 28th St. will be available for short detours. This construction is currently scheduled for 2025. View the proposed design.
