The PennDOT Office of Public-Private Partnerships will accept proposals throughout October, with parties needing to submit their ideas by October 31 to be considered by the agency in its latest round.
Under the regime, the private sector may also submit applications for non-PennDOT-owned assets directly to the P3 board.
PennDOT has two windows for unsolicited proposals every year, the other being in April. However, since the last window closed, the department has faced a difficult time on its P3 plans, with the flagship Major Bridge program needing to go back to the drawing board after it lost a court case in relation to its plans to toll the roads.
Since then, a new plan has emerged that will see the state fund the project through shadow tolls - but the change has meant some bridges have been dropped from the proposed contract.
