IH-45 North Reconstruction Schematics

Created and last updated 1-May-2001

These schematics were taken from the TxDOT web site and are a final design

This $27.9 million widening project is the latest in a series of projects to upgrade IH-45 in the vicinity of the Woodlands, which is 30 miles north of downtown Houston. The project will be awarded in June 2001. This project will expand the freeway to 8 continuous main lanes, 6 feeder road lanes, and a wide paved center section for a future HOV lane. This project is urgently needed to relieve congestion on this section of the freeway, which currently has 4 main lanes and 4 feeder lanes. According to the TxDOT unified transportation plan, this is the northernmost section that will be upgraded to 8 main lanes. North of this section, present plans show that the freeway will be upgraded to 6 main lanes all the way to the Montgomery/Walker county line, which is about halfway between Conroe and Huntsville.

The map below summarizes the projects in progress on IH-45 north. A total of $160 million in work is currently in progress.
