(a) Enforcement of traffic laws.--To the extent the public-private transportation project is a highway, bridge, tunnel overpass or similar transportation facility for motor vehicles, 75 Pa.C.S. (relating to vehicles) and other laws of this Commonwealth or, if applicable, any local jurisdiction shall be the same as those applying to conduct on similar transportation facilities in this Commonwealth or the local jurisdiction. Punishment for offenses shall be prescribed by law for conduct occurring on similar transportation facilities in this Commonwealth or the local jurisdiction.

(b) Arrest powers.--All officers authorized by law to make arrests for violations of law in this Commonwealth shall have the same powers, duties and jurisdiction within the limits of a public-private transportation project as they have in their respective areas of jurisdiction. The grant of authority under this section shall not extend to the private offices, buildings, garages and other improvements of a development entity to any greater degree than the police power extends to any other private offices, buildings, garages and other improvements.
