The 183N Mobility Project involves construction of two express lanes in each direction along US 183, extending from SH 45N/RM 620 to State Loop 1 (approximately nine miles), and the addition of a fourth general-purpose lane in areas where there is not one currently. The project also includes building auxiliary lanes, shared-use paths, sidewalks, and bicycle/pedestrian facilities. The express lanes will allow Capital Metro to increase bus service during peak periods. Capital Metro recently announced its purchase of almost 200 new electric buses, which will be utilized in the corridor.

  • Variable toll pricing will be used to keep traffic in the express lanes moving at least 45 miles per hour. Public transit buses, emergency responders, Capital Metro registered carpools and vanpools, MetroAccess vehicles, and State and Federal military vehicles will be able to use the 183 Express Lanes without paying a toll.
  • The project is being procured using a design-build approach. The contractor is responsible for both producing the roadway design and constructing the project. The design-build delivery method can improve efficiencies, reduce costs, and provide a timelier project completion.
  • The $250 million TIFIA loan for the 183N Mobility Project is actually the second TIFIA loan to the Central Texas Regional Mobility Authority under President Biden. The first financed three of their projects including 183A Phase III, 183S and 290E Phase III.
