A portion of 54th Avenue is closed in Seminole while Pinellas County crews repair a leak in a 24-inch sanitary sewer force main.

The road is closed between Seminole Boulevard and 110th Way. Drivers are urged to use alternate routes.

Those needing to access Keswick Christian School at 10101 54th Ave. N. can do so from Tyrone Boulevard through 100th Way only.

Sewer service in the area has not been affected. Officials weren't sure how long the repair will take.

Officials said the leak developed Monday at about 10 p.m.  The leak has since been contained.

The repairs may take up to three weeks, officials say.
