Speed limits on the Pennsylvania Turnpike

Pennsylvania’s transportation law, Act 89, enacted in 2013, allows the maximum speed limit on freeways within the Commonwealth to be raised to 70 MPH after completion of appropriate engineering evaluations. On July 22, 2014, The Pennsylvania Turnpike changed the maximum speed limit on the mainline Turnpike, in a section between the Blue Mountain Interchange (Milepost 201) and the Morgantown Interchange (Milepost 298), to 70 MPH as part of an initial evaluation.

On May 3, 2016, the Pennsylvania Turnpike changed the maximum speed limit to 70 MPH on all sections of the Turnpike that were previously 65 MPH. An engineering evaluation to determine the speed for each curve on the mainline Turnpike, Northeast Extension (I-476), Beaver Valley Expressway (I-376), Amos K. Hutchinson Bypass (Turnpike 66), the Mon-Fayette Expressway (Turnpike 43) and the Southern Beltway (Turnpike 576) was performed.

In addition to the new 70 MPH speed limit signs, new curve warning signs with advisory speeds have been installed prior to each curve where a reduction in speed is recommended. Speed and crash evaluations will continue, but no adverse impacts have been found to date.

Please remember, 70 MPH (or any posted speed limit) is the maximum speed; you should drive at lower speeds during adverse traffic, weather or roadway conditions.
