If you have any intention whatsoever to drive this weekend anywhere close to the Katy Freeway – West Loop interchange, you need to reconsider.
As a part of the ongoing Katy Freeway expansion project, the Highway Department will close the Katy freeway near the West Loop interchange from 9 p.m. tonight through 9 p.m. Saturday for eastbound lanes and from 9 p.m. tonight to 5 a.m. Monday for the westbound lanes so that workers can demolish a portion of the North Post Oak Road bridge. As a result, drivers will face detours via side streets and frontage roads with traffic jams likely to snarl near west Houston and the Galleria area all weekend.
If you absolutely must drive in this part of town over the weekend, I recommend highly that you bring a good book to read while you sit in traffic.
