I-45 (NASA 1 Bypass to South FM 518)

This construction project includes improvements on I-45 from NASA 1 Bypass to south of FM 518, in Harris and Galveston counties.

Planned Construction Improvements

Planned improvements include the following:

Reversing and braiding the northbound entrance and exit ramps; this means the northbound entrance and exit ramps will be reversed, and the northbound entrance ramp will go over the northbound exit ramp
Widening northbound exit ramp to a two-lane exit ramp
Lengthening Clear Creek frontage road bridges
Constructing detention ponds

Approximately six acres of additional right of way are required for the proposed design changes. No additional displacements are anticipated.
