The Transportation Improvement Program (TIP) is the Lehigh Valley’s $484 million four-year plan to maintain and enhance the transportation system in Lehigh and Northampton counties. It is updated every two years and this update is just one part of an overall plan to create a seamless network where roads, trails, sidewalks, technology and transit connect everyone to every place. The TIP is critical to the economic and social future of the region, targeting infrastructure investments that support a vibrant, inclusive, resilient and growing Lehigh Valley. The comment period ran May 2 to May 31, and included several ways to participate, found on page 7 of the TIP Made Easy.


In anticipation of updating the 2025-2028 Transportation Improvement Program, the LVTS will meet to create the draft TIP across two or three workshops in December 2023.

Annual List of Obligated Projects + Accomplishments

This listing shows all money obligated for highway, bridge, transit, bicycle and pedestrian projects within Lehigh and Northampton counties Federal Fiscal Year (FFY) 2023. The use of federal transportation funding is authorized by the current multi-year transportation bill approved by Congress and the Infrastructure Investment and Jobs Act (IIJA). It allows the US Secretary of Transportation to authorize funding to Metropolitan Planning Organizations (MPOs) across the US, through the Federal Highway Administration (FHWA) and Federal Transit Administration (FTA). Federal funding is then allocated to states based primarily on population data from the US Census Bureau. State allocations are then distributed to individual MPOs and Rural Planning Organizations (RPOs) based on formulas developed by the Pennsylvania Department of Transportation (PennDOT) and representatives of MPOs and RPOs. These formulas take into account population, vehicle miles traveled, truck vehicle miles traveled, roadway surface conditions, lane miles, structurally deficient bridges, all bridges and the region’s air quality classification.
