Karston Thot Bridge, on the northern end of Kamehameha Highway on the way from Wahiawa to the North Shore, will be closed from 9 tonight to 4 a.m. tomorrow.

The closure will allow the state Department of Transportation to do electrical repairs and routine bridge maintenance.

North Shore-bound motorists are advised to proceed to the end of H-2 Freeway, and take Wilikina Drive to Kaukonahua Road (Waialua-bound) or to Kamananui Road and Kamehameha Highway (Hale'iwa-bound). Honolulu-bound motorists coming from the North Shore are advised to take Kamehameha Highway south to Kamananui Road, make a left turn on Wilikina Drive, and proceed to H-2 Freeway in the south-bound direction.

Motorists are advised to use caution while driving through the work area and to allow for extra travel time.
