Sixteen Key Roadways have been identified by the Regional Traffic Planning Task Force as the spine network for the study’s detailed evaluations. They are major roadways, or roadways of specific concern, serving local and through travel in the study area which carry the highest traffic or truck volumes or are particularly sensitive to the volumes. In total, 70 miles of State owned and maintained highways are represented in the set of Key Roadways.

The individual roadway segments are described below:

1. Worthington Mill Road (SR 2081); Wrightstown and Northampton Townships
2. Swamp Road (SR 2036); Wrightstown and Newtown Townships
3. Lindenhurst Road (SR 2069); Lower Makefield, Upper Makefield, and Newtown Townships
4. Stoopville Road (SR 2028); Wrightstown, Newtown, Upper Makefield, and Lower Makefield Townships
5. PA 413 (SR 0413, Durham Road) between Newtown Bypass and Township Line Road; Newtown and Wrightstown Townships
6. Newtown Bypass between I-95 and Swamp Road; Lower Makefield and Newtown Townships
7. Newtown-Richboro Road / Jacksonville Road (SR 0332); Newtown and Northampton Townships
8. Second Street Pike (SR 0232) between Bristol Road and PA 413; Wrightstown and Northampton Townships
9. Bustleton Pike (SR 2065) between Bristol Road and PA 232; Northampton Township
10. Wrightstown Road (SR 2081) between PA 413 and PA 532; Wrightstown and Upper Makefield Townships
11. Mill Creek Road / Washington Avenue / Cherry Lane (SR 2091) between Swamp Road and PA 232; Wrightstown Township
12. Township Line Road / Mill Creek Road (SR 2115) between PA 413 and Washington Avenue; Wrightstown Township
13. Newtown Bypass / Durham Road / Washington Crossing Road (SR 0532) between Swamp Road and Taylorsville Road; Newtown, Lower Makefield, and Upper Makefield Townships
14. Taylorsville Road / Main Street / Yardley-Morrisville Road / Pine Grove Road (SR 2071) between PA 32 and Trenton Avenue; Upper Makefield and Lower Makefield Townships, and Yardley Borough
15. PA 332 (SR 0332) between I-95 and PA 32; Lower Makefield Township and Yardley Borough
16. PA 32 (SR 0032, River Road) from Lurgan Road to Taylorsville Road, and from PA 532 to Trenton Avenue; Upper Makefield and Lower Makefield Townships, and Yardley Borough

In total or in part, they will be the subject of very specific engineering evaluations conducted in compliance with PennDOT’s procedures. These studies include:

• Weight, Size & Load Restriction Studies - to judge the integrity of all 16 Key Roadways
• Traffic Engineering & Safety Studies - to determine the safety and efficiency of Swamp Road in its entirety, and the remaining segments of the Key Roadway network which serve heavy truck volumes
• Traffic Calming Feasibility Studies - to determine the role, if any, that traffic calming measures can play in addressing the truck and traffic issues on the Key Roadways

Where recommendations are identified, particularly traffic calming measures, the study will consider the possible traffic effects which might cascade to secondary roadways.
