Route 251 north of Mendota will be under construction so workers can replace a bridge and install box culverts.
Work is scheduled to begin Tuesday at the bridge over Pike Creek north of Route 34 and the structure over the drainage ditch south of North 45th Road.
If you take that way, expect to find temporary traffic signals.
The $940,000 project is being done by D Construction. It should be completed by the end of August.
