Losing a traffic lane is not cheap. That said, allowing buses to use additional lanes has significant benefits. One of the best ideas I have seen is only allowing buses to use the break down lane. Opening them up to normal traffic risks major delays after an accident and often the real issue is off ramps not though traffic, but a bus can get around the occasional broken down car with minimal delays while significantly increasing a roads capacity. Also adding bus specific shortcuts can provide major benefits for minimal cost.
