Night owls and early birds in Cary should brace for a series of detours as the N.C. Department of Transportation has announced upcoming closures at the I-40/I-440/U.S. 1 interchange for soil testing activities, with each ramp closing for one night from Sunday through Wednesday between the decidedly inconvenient hours of 11 p.m. and 5 a.m., conditions permitting. According to the NCDOT, the scheduled work is part of a broader initiative to maintain and improve highway infrastructure in the area.

The traffic diversions, set to affect the sleep cycles of commuters next week have been detailed, with Sunday seeing U.S. 1 North and I-440 West motorists needing I-40 East being rerouted to I-40 West to Exit 291 and back, while Monday's detour will push those on I-40 East who want U.S. 1 South through a reminiscent of a pinball's course change ramps through interchange (293B, 1B, then 293A) to reach their destination.

In what reads like a traveler's nighttime labyrinth, Tuesday and Wednesday won't spare the weary; I-440 West drivers aiming for I-40 West will negotiate a detour involving a sequence of ramps at the interchange (1A, 293B, then 1B), and those on I-40 West will be diverted to I-440 East through another complex dance of roadways (293A, 1A, then 293B).
