Coverage Limitations

• Local roads: Local governments are the posting authorities for locally owned roads. Not all municipalities report to PennDOT, and those that do not report may not appear in this workbook. Check directly with the relevant county or municipal authority for locally owned road restrictions.
• Bridges: Bridges are posted independently of roadways. This workbook does not cover bridge postings. Consult PennDOT's bridge-posting records separately before routing over structures.
• Absence does not mean clear: If a road does not appear in this report, that does not confirm unrestricted access. Verify route-specific clearance with the appropriate authority before dispatch.

Dispatch Action Items

• Restrictions are active now. All 26 posted segments are confirmed active in 13 counties as of 3/11/26. Do not route heavy freight over listed roads without confirming your GVW is within the posted limit.
• 10-ton GVW is the most common limit. A standard loaded semi-trailer will almost certainly exceed 10 tons. Treat any 10-ton listed route as off-limits unless you have confirmed compliance or a valid permit/bond.
• 8-ton limit on Union SR 1001. The most restrictive posting in this report applies to a specific 0.742-mile segment. Avoid this segment entirely with any loaded commercial vehicle.
• Bonding may be available. Pennsylvania law allows haulers to operate on posted roads under bond. Contact PennDOT BOO to confirm bond procedures if you must use a posted road.
• Financial liability applies. Operating on a posted road without authorization or bond exposes the hauler to financial responsibility for any road damage caused.
• Download the current report directly from PennDOT BOO for the most up-to-date posting list: Statewide Posted Road Report (XLSX).
• Check bridges separately. This report does not cover bridge weight postings always verify bridge clearance independently.
