HUNTSVILLE – Big changes will be coming to the intersection of IH 45 and FM 1374/Montgomery Road in Huntsville as crews prepare to demolish the existing bridge and build a brand-new one. To keep traffic flowing during construction, a temporary roundabout-style traffic pattern will be introduced using the newly built U-turn bridges.
The main bridge that crosses IH 45 at FM 1374 will be removed and replaced. While this work is underway, drivers will use a roundabout-style configuration (see map below) to move through the intersection. This setup will rely on the recently completed U-turn bridges to keep traffic moving safely and efficiently. Signage will be in place to guide drivers through the intersection.
Key Dates to Know:
• Saturday, October 11, 2025 – Roundabout Traffic Pattern Begins
o Lane closures on IH 45 frontage roads and FM 1374 from 8 a.m. to 5 p.m.
o New traffic pattern goes into effect
• Friday, October 17, to Sunday, October 19, 2025 – Bridge Demolition Weekend
o Full closure of IH 45 main lanes from 8 p.m. Friday to 10 p.m. Sunday
o IH 45 Northbound traffic will exit at Exit 114 and re-enter north of Smither Drive
o IH 45 Southbound traffic will exit at Exit 115 and re-enter south of FM 1374
Construction of the new bridge is expected to be completed by late January 2026. Once open, traffic will return to a more conventional flow across IH 45.
