MADISON, Wis. (AP) — New 70 mph speed limit signs are being posted this week on interstates and highways in Wisconsin this week.

The state Department of Transportation said Monday that crews will start installing about 470 updated speed limit signs on Tuesday.

About 810 miles of Wisconsin interstates and highways will have speed limits increased to 70 mph from the current 65 mph. The DOT says drivers can start accelerating on designated roads once the signs are posted. All signs are expected to be in place Wednesday.

A DOT spokesman said more freeway segments could be signed for 70 mph speeds in the future.

Gov. Scott Walker signed into law last month the measure that allows the DOT to decide which highways can post increased speeds.
