IH-45 Traffic Conditions

TX-DOT announced some significant highway closures THIS SATURDAY in the League City area that could impact access to the UTMB Health League City Campus and other clinics in the region.

TxDOT will perform a total closure of I-45 this Saturday morning, November 12, to set the remaining two overhead sign structures near the SH 96 overpass.

This work will include a total closure of the northbound main lanes on Saturday from 6 am to noon, and a short-term total closure of the southbound main lanes only when setting the structures.

TxDOT is also switching the northbound main lane traffic to the permanent configuration from north of FM 517 to north of SH 96 this weekend. This work will be performed from Friday at 9 pm to Monday at 5 am. It will include an alternating northbound two-lane closure from FM 517 to north of SH 96, and closure of the following ramps:

• NB FM 518 exit
• NB FM 646 entrance
• NB SH 96 exit
• NB FM 517 entrance

The northbound FM 646 exit ramp will remain open all weekend. This will serve as the exit during the total closure and the detour for the SH 96 and FM 518 exits all weekend during the traffic switch.

The SH 96 entrance ramp will also remain open all weekend for traffic to re-enter the northbound lanes. Southbound traffic will exit to SH 96 during the short-term total closure and be able to re-enter via the SH 96 entrance ramp. TxDOT will provide off-duty officers to assist with traffic flow at the FM 517, FM 646, and SH 96 intersections.

Please check Transtar and other online traffic monitoring tools to plan accordingly and avoid slowdowns. As always, highway work is weather dependent and closures may be adjusted accordingly.

TX-DOT announced some significant highway closures THIS WEEKEND in the League City area that could impact access to the UTMB Health League City Campus and other clinics in the region. The work will be concentrated on IH-45 between FM 518 and FM 517, and is scheduled to begin on Friday, Aug. 26 at 9 p.m. and conclude Monday, Aug. 29 at 5 a.m. 

The closures will enable a contractor to apply final striping on the southbound main lanes from south of FM 518 (in League City) to north of FM 517 (in Dickinson). It will affect travel lanes and entrance and exit ramps. Here's what's planned for this weekend: 

IH-45 Gulf Freeway:

1. Alternating closure of two southbound main lanes from north of FM 518 to south of FM 517. No detour is required, as one southbound main lane will remain open, but slowdowns will be likely. 
   
   
2. Total closure of the southbound main lane ENTRANCE ramps between FM 518 and FM 517. Detour – Motorists can enter the southbound mainlanes south of FM 517 using the entrance ramp from FM 517, but the feeder lanes in the area may be congested and slowdowns are likely.  
   
   
3. Total closure of the southbound main lane EXIT ramps ramps between SH 96 and FM 517.
   Detour – Motorists can exit the main lanes using the southbound exit to SH 96 or the exit to Holland Road, as these will remain open.

Please check Transtar and other online traffic monitoring tools to plan accordingly and avoid slowdowns. As always, highway work is weather dependent and closures may be adjusted accordingly.

TXDOT announced a lane closure for next week on IH-45 southbound near Tiki Island, on the approach to the Galveston Causeway.

Beginning Monday, July 18  until Friday, July 22, one outside southbound lane will be closed from 9 a.m. to 3 p.m. daily.

The work will center on the BNSF railroad overpass. The work is being scheduled to reduce the impact to morning commuters heading to the island; two lanes southbound will remain open during the construction.  

Remember schedules can change. Please check road and traffic conditions when headed to or leaving the Galveston campus, and allow additional time as necessary. 

TXDOT announced lane closures next week in the I-45 northbound main lanes near Galveston. On Tuesday and Wednesday, July 5-6, from 9 a.m. to 3 p.m., two lanes will be closed on I-45 northbound near Galveston. The Tiki Island exit ramp lane and the outside travel lane will be closed from 9 a.m. to 3 p.m. on both days.

On Thursday and Friday, July 7-8, there will be alternating single lane closures in these two lanes. The work is part of a project to replace the Santa Fe overpass bridge.

Remember schedules can change. Please check road and traffic conditions before leaving the Galveston campus, and allow additional time as necessary. 

As of Weds., May 18, three southbound lanes on I-45 into Galveston have been opened, alleviating some of congestion facing morning commuters. However, only two lanes were open northbound, off the island, still creating a bottleneck on the Galveston Causeway during afternoon/evening commutes. The Texas Department of Transportation (TxDOT), which has active construction on  I-45 throughout Galveston County, is working toward opening and maintaining three lanes northbound and southbound, while work continues in the area near Tiki Island for the next two years.     

As another hot weekend approaches, it’s highly likely the island will experience a large influx of visitors, and it could affect traffic. Please check road and traffic conditions before coming to the Galveston campus, and allow additional time as necessary. Please be safe and exercise caution and patience while driving through highway construction zones.
