A portion of East First Road in Hope Township, between Route 18 and North 1250th Road west of Lostant, will be closed at least a week starting Wednesday, Aug. 24.

The La Salle County Highway Department said in a news release Thursday that the roadwork will take seven to 10 days to complete, weather permitting, with a target completion date of Aug. 31.

Motorists are advised to seek alternate routes. Detour signs will not be posted, the department said.
