The TxDOT Houston District is proposing to reconstruct and widen Interstate 45 (I-45) from Farm-to-Market Road (FM) 1764 to the Galveston Causeway in Galveston County, Texas. The proposed project will improve the existing roadway to enhance safety and mobility along the highway by reducing traffic congestion and improving the evacuation capability of the highway in instances of flooding and severe weather.

Current Conditions

Currently, I-45 is a six-lane, divided highway with frontage roads along both sides. The existing roadway consists of six main lanes, three in each direction, with 10-foot shoulders. There are four frontage lanes, two on each side of the highway, and drainage ditches running parallel to the roadway.

Proposed Improvements

• Reconstruction and widening of I-45 to include eight main lanes with two two-lane frontage roads
• Reconstruction of the I-45/SH 146/SH 6 Interchange at the Texas City Wye
• Construction of 6 detention ponds

Additional Information

The project requires approximately 19.7 acres of additional right-of-way, including 3 potential commercial displacements.
