If you're traveling over the Coleman Bridge in the wee hours of Sunday morning, take a book.

Or plan on taking a nap, playing Candy Crush Saga on your iPhone, or whatever. Electrical-mechanical work on the bridge could cause full-on traffic stoppages in both directions of up to 30 minutes, said a Virginia Department of Transportation spokeswoman.

The traffic stops are scheduled between 1:30 a.m. and 5:30 a.m. After each stop, crews will reopen the bridge to allow traffic queues to clear, the spokeswoman said.

Maritime traffic will not be affected.
