Overnight closures to rebuild I-10 at North Mesa Street (SH 20) will begin the first Monday in December. For several nights starting Dec. 4, from 9 pm each night to 6 am each morning:
- North Mesa will be completely closed in both directions under the I-10 Overpass
- I-10 West will be completely closed at North Mesa
- I-10 East will be reduced to one lane at North Mesa
The good news is all lanes will be open during the day. So be sure to wrap up your holiday shopping and head home by 8:45 pm to avoid the detour. Scroll down to see the detour illustration.
UPDATE: Originally, the intersection was scheduled to be closed for 11 nights
- Sunday, Dec. 4 through Thursday, Dec. 8
- Sunday, Dec. 11 through Thursday, Dec. 15
- Sunday, Dec. 18
Due to the delayed delivery of materials, the closures set for Dec. 12 and afterward will no longer take place. Instead, the contractor will reschedule for early January.
What’s happening at the I-10/North Mesa Intersection?
The I-10/North Mesa intersection will undergo three phases of construction, with the first phase entailing the construction of a new center bridge between I-10 eastbound and I-10 westbound. In the image, you can see support columns are already up, waiting for the new center bridge. In the subsequent phases, crews will rebuild the existing eastbound/westbound lanes.
During the December night time closures, crews will be moving 30 massive bridge beams into the area and using two cranes to set those beams into place. The longest beam is 164-feet long (about half the length of a football field); approximately 6 feet, 10 inches tall (about the height of Magic Johnson); weighs 57 tons (about the weight of seven T-Rexes), and will completely span North Mesa Street (SH 20) once it is in place. During the January night time closures, crews will install bridge deck panels and more to finish I-10’s new center median bridge.
What can motorists do during the night time closure of this intersection?
The GO 10 team recommends people try to avoid this intersection during these night time closures because the detour is no fun. If you must use this route, we’ll have detour signs in place.
