This routing required some major infrastructure work on US 22 west of Downtown Pittsburgh (particularly at the US 22/US 30 cloverleaf in Robinson Township) and safety improvements to PA 60; though both were limited access freeways before the extension, they were not up to Interstate Highway standards in all areas. The improvements to both the US 22/US 30 cloverleaf in Robinson Township and the Lawrence County leg of the route, as well as replacing all of the signs with the I-376 shield, were funded by the American Recovery and Reinvestment Act of 2009.
