Part of State St. in downtown Erie will be closed this week for water system improvements, Erie Water Works announced Monday.

The street will be closed between 4th and 5th St. in both directions Tuesday, Sept. 21, through Friday, Sept. 24, from 7:30 a.m. to 3 p.m.

State St. will only remain open to local businesses in the area. Some lane restrictions may remain in place at night.

Erie Water Works is asking drivers to avoid the area and to expect delays.

Water service for customers in the area may be affected at times while the work is completed.

The project is part of the Erie Downtown Development Corporation (EDDC) project.
