Three global firms bid to advise on 30km PPP scheme as tender terms require toll-road experienceBahrain’s planned 30km Northern Link Road could bring road tolls into play for the first time, with firms bidding to advise on the scheme required to show past work on highways or bridges funded by toll income. Each financial and technical adviser must show work on at least one major highway or bridge PPP scheme involving toll revenue. That leaves toll funding among the models likely to be studied as the government weighs how the Northern Link Road should be built, paid for and run. The Northern Link Road is planned as an east-west route running for about 30km, parallel to Sheikh Isa bin Salman Highway. The road is expected to cater for large housing and property schemes along the northern coast, among them Nurana, Marassi Al Seef and North Star.
