The tolled portion of I-376 is the most expensive portion of the Pennsylvania Turnpike system per mile, charging toll-by-plate users an average of 44 cents/mile and E-ZPass users 20 cents/mile. This is in stark contrast to the mainline Turnpike, which charges less than 12 cents/mile for E-ZPass users and more than 17 cents/mile for cash users. This is due to the bonds on newer sections of the Turnpike system (such as the James E. Ross Highway, Amos K. Hutchinson Bypass, Mon–Fayette Expressway, and the Southern Beltway) having not been paid for yet (in the case of the latter two, are only partially completed), whereas the mainline Turnpike and the Northeastern Extension had their bonds paid for decades ago. Even with the newer sections factored in—most of which except for a portion of the Mon–Fayette Expressway from I-70 near Bentleyville to US 40 near Brownsville opened "after" the James E. Ross Highway opened—it is the most expensive portion of the Turnpike system per mile.
