All the traffic at this point is crossing the border, now that both Romania and Bulgaria are in Schengen, no border checks either, and the cars are going pretty slow and do stop to ask where you're going. Be aware that at the time of my crossing, the bridge was getting renovated, and only one way was open, might be difficult to cross on foot if you wanted to, and might make the waiting times longer. But you can walk up to people and ask to take you!
