Reopen Manhole Covers

As you near the end of the game, you will obtain Doc's eye. Go back to the safe house and proceed through the kitchen, at which point you'll find all fast track routes closed. You can open them again, though, by heading back to each cleared area from the safe house. Find the manhole covers and open them once again. That will help you out a lot in the very near future.
