congested Squirrel Hill Tunnel. The western spur would have continued the PA Turnpike 43 routing while the eastern spur would have continued the PA Turnpike 576 routing from the routes' planned junction approximately south of Finleyville Elrama Road. Kennywood acquired nearly of property for a potential expansion of the park on the condition that the leg to Monroeville is built. After environmental clearances were obtained and right-of-way acquisition had begun, the project was placed on hold due to lack of funding. Current estimates for this section are in the neighborhood of $3.6 billion and funding has not been identified. A public-private partnership was explored but nothing feasible resulted. It is unlikely that any new construction will commence in the near future unless a new tax is imposed or private funding identified, although funding was secured for the section of PA Turnpike 576 in between Interstate 79 and its current eastern terminus at US 22, bringing hope for an eventual completion of the Mon–Fayette Expressway. In July 2013, the Allegheny County portion of the expressway was again the subject of news articles indicating that a change in approach may be taken. This revised approach would allow for completion of the expressway to Monroeville. The spur to Pittsburgh would not be constructed but rather the East Busway would be extended to Monroeville to allow for park and ride into downtown Pittsburgh. Another option currently being considered is to open the Busway to high-occupancy vehicle (HOV) traffic. In May 2013, a raise in the oil tax cap in Pennsylvania was proposed in the Pennsylvania General Assembly to fund additional transportation projects, including completing the Mon–Fayette Expressway and the Southern Beltway, as part of a larger transportation bill to help fund projects in the state. Pennsylvania Governor Tom Corbett signed a modified version of the bill into law, known as Act 89, on November 25, 2013, after much debate in the General Assembly that nearly killed the bill before it was passed. Act 89, which local politicians acknowledged that without passage would have killed the remaining segments of the Mon–Fayette Expressway, is expected to provide funding to complete the Southern Beltway all the way to the Mon–Fayette Expressway and provide a little less than half of the $2.2 billion (as of December 2013) needed to complete the Mon–Fayette Expressway, as well as the option for P3 funding. It was also acknowledged that like the
