MADISON, Wis. (AP) — A proposal that would raise the speed limit on Wisconsin's interstates to 70 miles per hour continues to race through the Legislature. The Assembly passed the bill earlier this month. A Senate committee plans to hold a public hearing on the measure Thursday and the full Senate could vote on it in November. The bill would give the state Department of Transportation six months to change interstate speed limits from 65 to 70. The agency would have to submit a study to the Legislature within a year on the feasibility of raising the limit to 70 mph on other four-lane highways. Democratic opponents have raised safety concerns with increasing the speed limit, but backers say most people already drive that fast now anyhow.
