Traffic Control Plan in Place
Sections of 21st Street will be closed due to utility work, but traffic flow will continue. West bound traffic on 21st Street from University Avenue to Whitis Avenue will be reduced to one lane from February 26th to April 5th. East of University Avenue will remain two-way. The southbound lane of University Avenue from 21st Street to 22nd Street will be closed for the duration of construction which lasts through Spring of 2028. Please follow the detour signage posted.
Two-way traffic will be provided on the north side of 21st Street from University Avenue to Wichita Avenue from February 26th to March 7th and will resume to the normal two way traffic flow starting March 8th.
Parking on the south side of 21st Street from University Avenue to Wichita Avenue will not be available. Motorcycle parking on the north side of 21st from University Avenue to Wichita Avenue will also be closed.

Project Summary
The Dobie Center garage phase has been completed; making way for the next phase, which is the installation of underground utility infrastructure for the new Undergraduate School of Business. This new underground utility infrastructure phase will include new Water and Sewer Lines connected to the City of Austin system. Additional Electrical and Telecommunications lines to be added to the existing duct bank. New Thermal Lines will be added and connected to the existing UT Thermal and Tunnel System. This underground utility infrastructure will support the 18-story Underground Business School. When the infrastructure phase is completed, the next phase will be adding two story underground garage and first floor slab.
Project Location: The Construction Site is located on W 20th and W 21st Streets and Whitis and University Avenues.
Project Impacts
Pedestrian Impacts: Pedestrians will be rerouted to the west side of Whitis Avenue, the south side of 20th Street, and the east side of University Avenue due to sidewalk closures. These sidewalk closures may vary depending on the underground utility work being performed. What will not change is that the sidewalks on the east side of Whitis Avenue, the north side from 20th Street from Whitis Avenue to University Avenue, and the west side of University Avenue from 20th Street will be fenced in and not accessible to pedestrians.
Travel Impacts: The project will involve several significant closures to facilitate construction and ensure safety. Whitis Avenue's northbound lane and University's Southbound Lane between 20th and 21st streets will be closed intermittently depending on the work being performed. Traffic and Detour signage directing traffic to alternate streets accordingly will be posted. Street parking areas along Whitis, 20th, and University will be impacted. The initial phases of this construction include work to major utilities located in and around all adjacent streets. Additional intermittent, short-term road closures and traffic pattern adjustments will be necessary.
Bicycle Impacts: The project will not impact existing bike lanes or bike racks. There are no designated bike lanes around this project. Bicyclists are always encouraged to refer to the City of Austin Bike Map.
Parking Impacts: Street parking will be unavailable on the east side of Whitis Ave, the north side of 20th Street, and the west side of University Avenue.
Signage will be installed at key locations to assist with wayfinding. Due to the fluid nature of construction, this information is subject to change, but we will do our best to provide timely communication if changes are necessary.
