UPDATE: PennDOT has lifted the temporary restrictions on certain vehicles from traveling on Interstate 80 in north central Pennsylvania.
Due to the winter storm impacting the region, PennDOT temporarily restricted certain vehicles from using the interstates earlier today to help ensure that the interstates remained open during the most challenging conditions of the winter storm.
The speed reduction of 45 mph has been lifted and speeds are restored to their posted limits.
Harrisburg, PA – While vehicle restrictions have been lifted in many areas of the state, several roadways in Northeast Pennsylvania still have restrictions in place, said the Pennsylvania Department of Transportation (PennDOT) and Pennsylvania Turnpike Commission. These restrictions will remain in place until conditions warrant their removal. Motorists are urged to avoid non-essential travel as crews continue their work to clear and treat roadways.
The following roadways have Tier 1 restrictions in place:
- Route 33 from Interstate 78 to Interstate 80;
- Interstate 78 from Route 33 to the New Jersey border;
- Interstate 81 from Interstate 80 to the New Jersey border; and
- Interstate 476 (PA Turnpike Northeast Extension) from Lehigh Valley Interchange (Interstate 78, Exit 56) to Clarks Summit (Interstate 81, Exit 131).
Under Tier 1 restrictions, the following vehicles are not permitted on affected roadways:
- Tractors without trailers;
- Tractors towing unloaded or lightly loaded enclosed trailers, open trailers or tank trailers;
- Tractors towing unloaded or lightly loaded tandem trailers;
- Enclosed cargo delivery trucks that meet the definition of a CMV;
- Passenger vehicles (cars, SUV’s, pickup trucks, etc.) that are towing trailers;
- Recreational vehicles/motorhomes;
- School buses, commercial buses and motor coaches not carrying chains or Alternate Traction Devices (ATD’s); and
- Motorcycles.
The following roadways have Tier 4 restrictions in place:
- Interstate 80 from Interstate 81 to Route 33;
- The entire length of Interstate 84; and
- Interstate 380 from Interstate 80 to Interstate 81
On roadways with Tier 4 restrictions in place, no commercial vehicles are permitted. Additionally, all school buses, commercial buses, motor coaches, motorcycles, RVs/motorhomes and passenger vehicles (cars, SUVs, pickup trucks, etc.) that are towing trailers are not permitted on affected roadways while restrictions are in place.
Additional speed and vehicle restrictions on these and other interstates could be added depending on changing conditions.
Restrictions will be communicated via variable message boards, the 511PA traveler information website at www.511pa.com and smartphone apps. Motorists can also sign up for alerts on www.511pa.com by clicking on “Personal Alerts” in the left-hand menu.
PennDOT and PTC are continuing their ongoing work to clear and treat roadways, and encourage that motorists avoid all unnecessary travel. Drivers should also be extra cautious around operating snow-removal equipment. When encountering a plow truck, drivers should:
- Stay at least six car lengths behind an operating plow truck and remember that the main plow is wider than the truck.
- Be alert since plow trucks generally travel much more slowly than other traffic.
- When a plow truck is traveling toward you, move as far away from the center of the road as is safely possible, and remember that snow can obscure the actual snow plow width.
- Never try to pass or get between several trucks plowing side by side in a “plow train.” The weight of the snow thrown from the plow can quickly cause smaller vehicles to lose control, creating a hazard for nearby vehicles.
- Never travel next to a plow truck since there are blind spots where the operator can’t see, and they can occasionally be moved sideways when hitting drifts or heavy snowpack.
- Keep your lights on to help the operator better see your vehicle. Also remember that under Pennsylvania state law, vehicle lights must be on every time a vehicle’s wipers are on due to inclement weather.
Temperatures are expected to remain near or below freezing, and winds are expected. With freezing temperatures, roads that look wet may actually be icy, and extra caution is needed when approaching bridges and highway ramps where ice can form without warning. If travel is necessary, motorists should generally reduce speeds, increase following distance, and be aware of changing conditions.
