SH 183 Managed Lanes - History
In 2004, TxDOT received an unsolicited proposal to improve SH 183 and IH-820. The agency moved forward with the elements in Tarrant County and began efforts to re-design the portions in Dallas County.
The modifications for the Dallas County portion were approved in April 2012. In June, 2012, the original SB 1420 committee authorized TxDOT to move forward with a toll concession project and a Request for Qualifications (RFQ) was issued. Due to the receipt of only one qualifications statement, TxDOT cancelled the existing procurement in January 2013.
