Lawmakers from New Jersey and Pennsylvania are proposing changes to the Delaware River Port Authority, which runs four bridges connecting the two states in the Philadelphia area.
The bills to be introduced in the legislatures of both states next week would ban the agency from doing economic development work and force it to comply with public records laws in both state, among other changes.
At the behest of the governors of both states, the DRPA has already made major changes in the last several years, including several included in the bills.
But sponsors say the rules must be made in law as well as agency regulations.
For the bills to take effect, it would have to be adopted in both states and approved by Congress.
The agency, which also runs PATCO train service, said its working to fix accessibility issues at stations. The agency recently began addressing issues on its trains by launching a new "Ride PATCO" mobile site.
Authorities such as the DRPA have received greater scrutiny since revelations that an official at the Port Authority of New York and New Jersey was involved in the politically motivated shutdown of lanes near the George Washington Bridge last year.
