HCTRA East Sam Houston Tollway Widening

HCTRA was created by Harris County Commissioners Court in 1983 after Harris County voters approved a referendum to construct, maintain, and operate toll roads in the rapidly growing Greater Houston Metropolitan area.

The East Sam Houston Tollway Widening project continues the widening from its current two lanes in each direction to four lanes in each direction between SH 225 and IH 45 South and will also include the construction of an inside safety shoulder and the reconstruction of tolled exit and entrance ramps.
