City of Lockport issued the following announcement on Jan. 18.
Priority Plowing System
The city has established a priority plowing system to help traffic move as efficiently and safely as possible.
Priority One streets are those that are main streets, including those in subdivisions, roads that link arterials, and those streets with schools located on them.
Priority Two streets are minor residential, side streets, and those cul-de-sacs with steep inclines and/or sharp curves.
Priority Three streets include dead ends, cul-de-sacs and alleys.
There are a number of roads within the city that are plowed and salted by the Illinois Department of Transportation, including Route 171 (State Street / Archer Avenue), Route 53 (Broadway), and Route 7 (159th Street / 9th Street), including the high level bridge. Will County plows Division Street east of Briggs and Briggs Street south of Division.
