183A Added Capacity Project

The purpose of the open house is to receive public comment on the Central Texas Regional Mobility Authority’s plan to evaluate a fourth lane in each direction of 183A Toll between RM 620 and Hero Way.

The open house will consist of virtual exhibits and an opportunity to comment. Comments must be received or postmarked by 11:59 p.m. on or before Sunday, Sept. 1, 2024, to be included in the official record of the virtual open house.

If you need additional information, the team is available by phone at 512-996-9778 between the hours of 9 a.m. and 5 p.m. Monday through Friday to answer questions about the project or open house. 

The Central Texas Regional Mobility Authority, in coordination with TxDOT, is conducting an environmental study for the addition of a fourth lane in the center median of 183A Toll in both directions between RM 620 and Hero Way.  An additional lane is a proactive measure that will allow for the 183A Toll Road to accommodate future traffic volumes and reduce anticipated traffic congestion due to the unprecedented growth of Cedar Park and Leander. The study area is a 9-mile segment of 183A Toll from RM 620 to Hero Way.

This virtual open house will share components of the roadway history, the environmental evaluation and analysis, and next steps.  

The open house will be conducted in English. If you need an interpreter or document translator because English is not your primary language or you have difficulty communicating effectively in English, one will be provided to you. If you have a disability and need assistance, special arrangements can be made to accommodate most needs. If you need interpretation or translation services or you are a person with a disability who requires an accommodation to attend and participate in the open house, please contact the Central Texas Regional Mobility Authority Team at 512-996-9778 no later than 4 p.m. CT, July 25, 2024. Please be aware that advance notice is required as some services and accommodations may require time to arrange.
