The city of Wooster says that a portion of Grosjean Road will be closed for most of next week for some gas line work. The closure will begin Monday and run through Thursday, lasting each day from 8am to 4pm. The actual work area will be between Spruce Street and the railroad bridge, meaning that businesses on the east side of the bridge will still be accessible from Timken Road. The city is also reminding motorists that the 90-day closure of Madison Avenue at the railroad bridge is also scheduled to begin on Monday.
