Senate President Pro Tempore Joe Scarnati said Friday he will introduce legislation soon to allow the higher maximum speeds on interstates.
The Jefferson County Republican says the 70 mph limit will make traffic move better and make the delivery of goods more efficient.
Scarnati says 34 states allow at least 70 mph, and 16 of those states cap speeds at 75 mph.
His proposal wouldn't mandate the higher speed limit. Speeds wouldn't be increased without justification by highway department studies.
Scarnati is seeking cosponsors for the legislation. Pennsylvania adopted the 65 mph limit in 1995.
