South Lamar Boulevard Corridor

The City of Austin, in coordination with the Texas Department of Transportation, is hosting a virtual public hearing for South Lamar Boulevard between Riverside Drive and US 290. The public hearing is a state requirement because the proposed improvements include the addition of bicycle lanes on South Lamar Boulevard, which is a state-owned roadway. 
 Visit AustinTexas.gov/SouthLamarENV between Wednesday, July 15 at 9 a.m. and Thursday, July 30 at 5 p.m. to learn the results of environmental studies that were conducted to evaluate proposed mobility and safety improvements, and provide your comments.  

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.
The City of Austin is currently conducting an environmental analysis of mobility and safety improvements on South Lamar Boulevard between Riverside Drive and US 290 to understand the potential impacts. The analysis was conducted in accordance with the National Environmental Policy Act for this state-owned roadway. If environmental clearance is received, construction of some projects could begin as early as late 2020.

Construction Phasing

Construction of improvements for the South Lamar Boulevard corridor will be phased in segments. While the bulk of construction is anticipated to occur between 2021-24, the Corridor Program Office (CPO) is evaluating opportunities to get improvements on the ground as soon as possible. View South Lamar Boulevard flyer - PDF.

  • Intersection improvements at Barton Skyway, Menchaca Road, Bluebonnet Lane, Oltorf Street, and Evergreen Avenue; will include improved crossing conditions and connectivity for pedestrians and cyclists, including enhanced and separated facilities 
  • Pavement rehabilitation and relocation of the existing curb closer to the centerline of the roadway. 
  • New shared-use paths for pedestrians and cyclists on both sides of South Lamar Boulevard that will comply with ADA guidelines 
  • Access management improvements such as intermittent-raised medians in some locations and driveway modifications 
  • Drainage improvements 
  • Bus stop improvements in partnership with Capital Metro, including a new dedicated transit priority lane northbound through the intersections at Barton Skyway and Menchaca Road
Construction is anticipated in Fall 2022.
Intersections at Del Curto Road/Bluebonnet Lane and Mary Street/Evergreen Avenue 
Improvements include: 
  • 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 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
  • 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

Public Engagement

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.  
Public feedback remains at the heart of our efforts to make this corridor safer and easier to travel. We will continue to engage the public throughout design and construction, share the latest plans with the community by various methods including: public meetings, stakeholder meetings, electronic updates, and more. We welcome your comments and questions, so please feel free to reach out to us:

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, inviting the owners and representatives of businesses located along the nine roadways where Corridor Construction Program improvements are planned to collect input on how the City can help reduce the impacts of construction. This input is being used to develop a Business Success Toolkit.  Additional engagement with South Lamar businesses is planned for 2020. 

Engaging with Property Owners 🏘️

In fall 2017, the CPO sent letters to all corridor-facing property owners along South Lamar Boulevard to share information about improvement plans. In 2019, as part of final design, we have been conducting meetings with potentially impacted property owners to share the latest information and obtain feedback, which will be used to refine improvement designs. These meetings are ongoing, and will occur to coincide with each construction segment’s project development process.

Public Meetings 🚪

On Monday, October 1, 2018, we hosted an open house meeting to share information about planned improvements for South Lamar Boulevard and obtain community feedback to refine the design of the improvements. The maps shared at the meeting were conceptual, as preliminary engineering was still underway. Click here to view the official Public Meeting and Community Feedback Report.

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.
