The state Department of Transportation says the Karsten Thot Bridge in Wahiawa will be open for northbound passenger traffic starting Monday. But only from 3 p.m. to 7 p.m. And only on weekdays.

The southbound (toward Honolulu) lane will still be available for morning commuters from 5 a.m. to 9 a.m. on weekdays.

The DOT says “critical structural work” is almost done but there is more sandblasting and painting needed. Officials are still hoping to fully re-open the entire bridge by the end of October. 

The 80-year-old steel bridge has been closed to traffic for weeks, causing snarls for people trying to get to and from the North Shore.
