Dallas-Fort Worth Metroplex
Texas Department of Transportation (TxDOT)
Highway / Express Lanes
The Midtown Express, formerly the SH 183 Managed Lanes Project, will increase the capacity and reconstruct portions of State Highway (SH) 183, SH 114 and Loop 12, which intersect one another southeast of Dallas-Fort Worth International Airport and northwest of Downtown Dallas. SH 183 is a critical east-west route between Dallas and Forth Worth originally built in the 1940s. The current roadway dates back to 1959, and has remained relatively unchanged since 1973 when one additional lane was added in each direction. Today, the highway serves as a primary connection between Dallas and Fort Worth, but it can no longer adequately meet the demand of 150,000 to 170,000 vehicles a day.
The project will increase the capacity of the three roadways with the addition of one TEXpress (toll managed) Lane in each direction:
The project will be delivered using an innovative public-private partnership. TxDOT will provide $600 million in progress payments throughout the estimated 3.5-year construction period to the private partner. The remaining $247.6 million will be financed by the private partner and paid in five installments over five years following substantial completion. TxDOT will collect all tolls on the express lanes and compensate the private partner for operating and maintaining a portion of the project for 25 years after substantial completion.
Additional plans for further expansion are also envisioned pending future funding availability.
Total project cost - $1,415.1 million (YOE, based on Initial Financial Plan)
O&M payments over 25 years (present value)
Federal funds - $680.5 million
State funds (motor fuels taxes, state vehicle registration fees, tolls/user fees, state and local bond programs, local governments' general funds) - $387.1 million
