Rush hour commuters be prepared:

The Illinois Department of Transportation announced Friday that First Avenue will be closed in both directions at the Canadian National Railroad crossing just north of Cermak Road for nine days starting Oct. 8.

The closure is to allow crews to reconstruct the railroad crossing at the site. The work will be done, weather permitting, between 6 a.m. on Oct. 8 and 6 a.m. on Oct. 17.

North and south traffic between Roosevelt Road and Cermak Road will be re-directed to Desplaines Avenue during construction. Motorists should expect delays.
