SR 400 Flex Lane Scheduled to Close Mid-March

Beginning March 17, 2023, the State Route (SR) 400 flexible shoulder lane, or flex lane, will no longer operate as an additional lane during peak-travel hours and will instead become a shoulder permanently.

As part of the closure, crews will remove the current flex lane signage and striping will become permanent shoulder striping. A reduced speed limit of 55 mph will also go into effect on SR 400 from the Northridge Road exit to the Kimball Bridge Road exit.

In addition to the work on the flex lane, a left-lane closure will be in place from 7 p.m. on Friday, March 17, 2023, until 7 p.m. Sunday, March 19, 2023, on SR 400 in both the northbound and southbound directions between approximately mile marker (MM) 13 to MM 15.

Motorists are advised to navigate this area with extra caution through the coming months as construction crews will be in the area.

These activities are for the SR 400 Phase 1 Design-Build project which replaces the Pitts Road, Roberts Drive, and Kimball Bridge Road bridges over SR 400. The three overpass bridges will be replaced with wider, taller structures to accommodate the future express lanes along SR 400. As part of the bridge replacements, multiuse paths will be incorporated into the new bridges. The updated structures will provide operational and local road improvements in advance of the major express lanes’ construction anticipated in 2024.
