Drivers will see new speed limits on much of the northern part of Interstate 93 starting Wednesday.
A law passed earlier this year increases the speed limit from 65 to 70 miles per hour north past Canterbury to the Vermont border.
The law goes into effect January 1.
The only exception is through Franconia Notch, where the speed limit will not change.
Department of Transportation spokesman Bill Boynton says signs for the new speed limits are already in place, and will be uncovered Wednesday.
But he says drivers should still use caution.
“Well, particularly in winter time, people still need to drive according to the conditions. That’s also under state law. It’s not a green light to go at unlimited speeds, especially in winter conditions.”
The state’s Highway Safety Agency and the Department of Public Safety opposed the bill.
