  • 8 p.m.-5 a.m. April 24: All northbound lanes will close from just north of FM 1314 to north of the the Grand Parkway and Hwy. 59 overpass.

Original post April 7:

As the Texas Department of Transportation moves forward on its $855 million project to expand the Grand Parkway from New Caney to Baytown, some Hwy. 59 lanes will temporarily shut down to allow construction crews to build bridges over the highway.


The work will be done in several phases over the next three to four months beginning on April 17-18, according to an April 3 news release from Grand Parkway Infrastructure, LLC, the contractor of the TxDOT project. During construction, portions of the Hwy. 59 frontage roads as well as northbound and southbound main lanes will be closed to traffic, per the release.

The first set of main lane closures will be the southbound lanes from just south of Walton Avenue to just north of FM 1314 on April 17 between 8 p.m.-5 a.m.; the southbound closure will begin at the FM 1314 and Porter/Conroe exit. The second set of main lane closures will be northbound lanes from just north of FM 1314 to north of the the Grand Parkway and Hwy. 59 overpass on April 18 between 8 p.m.-5 a.m; the northbound closure will begin at the Community Drive exit.

GPI Public Relations Manager Chris Neil said via email that all closures scheduled after April 18 will be posted on the project website, media advisories and on social media accounts. However, he did that the lanes will close periodically over the next few months.

"These lanes will be closed periodically when the crews engage in a number of critical activities, such as erecting bridge beams, setting deck panels, pouring concrete, installing railings and other miscellaneous activities," he said.


Grand Parkway segments H, I-1 and I-2—which span a 52.8-mile corridor—are set to open in spring 2022. For more information on the project, visit sh99grandparkway.com.
