South Lamar Boulevard Corridor
As part of mobility, safety and connectivity improvements, the City of Austin will incorporate elements that preserve and amplify the community’s identity and sense of place. Your feedback is requested to help inform placemaking projects on South Lamar Boulevard near Mary Street and along the stretch of roadway between Treadwell Street and Oltorf Street.
Click the links below to take the survey by 5pm on Thursday, June 24th.
Mobility, safety, and connectivity improvements are coming to South Lamar Boulevard between Riverside Drive and U.S. 290. As proposed, the City of Austin anticipates investing between $34 and $42 million from the 2016 Mobility Bond on the improvements, which are included in the Corridor Construction Program adopted by Austin City Council. The projects are expected to reduce vehicular delay, improve the effectiveness of transit, create continuous ADA-compliant sidewalks and continuous bicycle facilities along the entire length of the corridor.
Preliminary engineering is complete and the full design phase of work began in April 2019 when City Council authorized staff to finalize designs and prepare the projects for construction.
Construction of improvements for the South Lamar Boulevard corridor will be phased in segments. The bulk of construction is anticipated to occur between 2021-24, and the Corridor Program Office (CPO) is evaluating opportunities to get improvements on the ground as soon as possible.

Intersections at Del Curto Road/Bluebonnet Lane and Mary Street/Evergreen Avenue
- New roundabouts will be added at two intersections just east of South Lamar Blvd. to increase safety and enhance traffic flow and operations.
- Del Curto Road/Bluebonnet Lane: This improvement will route traffic desiring to head southbound on South Lamar Boulevard to turn left from Del Curto Road. Left turns onto southbound South Lamar will not be permissible from westbound Bluebonnet Ln.
- Mary Street/Evergreen Avenue: This improvement will route trafﬁc desiring to head southbound on South Lamar Boulevard to turn left from westbound Evergreen Avenue. Left turns onto southbound South Lamar will not be permissible from westbound Mary Street.
Construction is anticipated in Fall 2022.
UPRR Pedestrian Crossing east of Treadwell Street
- Improvements will require coordination with the railroad owner, Union Pacific, which is occurring during final design.
Construction is anticipated in Fall 2022.
Additional fieldwork and surveys will be performed as part of final design, so please be advised that you may observe workers and equipment along and near the corridor collecting data.
Preparing for Construction
In October 2020, the Texas Department of Transportation (TxDOT) notified the City of Austin that environmental clearance was issued for South Lamar Boulevard, clearing the way for the Corridor Program Office to proceed with construction of mobility and safety projects that are funded by the voter-approved 2016 Mobility Bond.
In April 2019, City Council authorized staff complete additional design and engineering to prepare projects for construction. Activities include:
- Developing corridor construction plans and preparing for construction by:
- Obtaining permits
- Developing traffic management plans
- Coordinating utility relocations
- Purchasing right-of-way
- Determining construction packaging, phasing and sequencing
- Obtaining permits
- Designing placemaking areas
- Completing environmental investigations and documentation
- Continuing to explore leveraging/partnership opportunities
- Conducting ongoing community engagement with neighborhoods, businesses and property owners to understand their priorities and concerns
Corridor improvements are informed by the community’s needs and input. Community engagement played a critical role in developing the Corridor Construction Program and the South Lamar Boulevard Corridor Mobility Plan. Public support for the corridor improvements was expressed through voter-passage of the 2016 Mobility Bond.
Virtual Public Hearing 💻
The City, in coordination with TxDOT, hosted a virtual public hearing for South Lamar Boulevard corridor in July 2020 to share the results of environmental studies that were conducted to evaluate proposed mobility and safety improvements.

Coffee on the Corridor ☕
The CPO held a Coffee on the Corridor meeting for South Lamar Boulevard at the South Austin Senior Activity Center on March 11, 2020. The community was invited to learn about planned mobility and safety improvements and upcoming construction on South Lamar Boulevard between Riverside Drive and Barton Springs Road. Additional Coffee on the Corridor meetings will be held as design plans progress on other corridor improvement projects.
Stakeholder Briefings 💼
The CPO has been meeting with various stakeholder groups to discuss improvements and obtain feedback. We are happy to schedule additional meetings upon request.
Engaging with Businesses 🏢
The CPO walked South Lamar Boulevard in late 2017 to share information about improvement plans with corridor businesses. We also conducted a series of Business Workshops in October 2018 to solicit input from corridor businesses regarding ways the City can help minimize disruptions during construction. Businesses who participated expressed a strong desire for good signage and communications during construction. CPO is committed to providing both, and we’ve used their input to inform this Construction Reference Guide. CPO will continue our engagement with South Lamar businesses throughout current construction projects, and in advance of future construction projects along the corridor.

Corridor Mobility Plan
The City of Austin finalized a Corridor Mobility Plan for South Lamar Boulevard in April 2016. This plan recommended short and long-term improvements for mobility and safety along the corridor. The Corridor Mobility Plan was the basis for development of the Corridor Construction Program.
We are actively pursuing funding through various sources to design and construct the improvements that complete the ultimate corridor vision. Potential funding sources include current and future bond funds, grants, partnerships and private investments.
