A detour in the City of St. Peter will continue for the first half of September. Washington Avenue between Riverview Road and Highway 169 in St. Peter has been closed for several weeks. Officials say it will now continue to be closed until Sunday, September 18th. The closure is part of a plan to make Washington Avenue a thru street and connect with Highway 169. The work also includes closing the inner lanes of 169 near Highway 99 for about a month so crews can build the new intersection for Washington Avenue. Those lanes will be closed beginning this Wednesday, September 7th.
