The intersection of 15th and Cedar in Ottawa will be closed Thursday as work is progressing on the 15th Street Storm Sewer project, city officials said.

The closure will allow Killough Construction to cross 15th Street on the east side of Cedar to install pipe. Thru traffic will be routed down to 13th Street over to Oak and back to 15th Street.

City officials expect the closure to last through the day with 15th Street opening back up by Thursday evening.
