Capital Express Project
TxDOT is currently working on 10 stand-alone projects between RM 1431 and SH 45SE, including:
- RM 1431 to FM 3406
- FM 3406 to US 79
- US 79 to SH 45N
- SH 45N to Grand Avenue Parkway
- Wells Branch Parkway
- Parmer Lane
- Rundberg Lane to US 290E
- 51st Street
- Oltorf Street
- Stassney Lane to William Cannon Drive
The Capital Express project would add two express lanes* in each direction and address all remaining safety and mobility improvements proposed under the Mobility35 Program that were not already included in the above stand-alone projects.
Two alternatives are being considered, an express lane build alternative and a no-build alternative. The build alternative could include placing the express lanes under the mainlanes where right of way is limited, providing direct access between the express lanes and frontage road, removing the upper decks from Martin Luther King Boulevard to Airport Boulevard and lowering I-35 through downtown.
Need & Purpose
*Dates are contingent on funding.
*Express lanes being proposed could include managed lanes, such as High Occupancy Vehicle (HOV) lanes, but do not currently include tolled management control lanes.
