Proposals are due August 14 from legal and financial consultants to advise the Pennsylvania Turnpike Commission on a P3 procure- ment for DBFOM delivery of a fiber optic network along the toll road’s 550-mile right of way. Statements of qualification from developers will be sought with the intent of signing an agreement next fall and starting construction by year end 2017. The commission expects the private developers to create a wireless mesh overlay and market excess trunk line capacity to help pay for the system.
