This city has an important road network but it is not connected to the "main" road network. For example currently no route can be found by car to Manaus (see https://www.openstreetmap.org/directions?engine=fossgis_osrm_car&route=-3.349%2C-64.710%3B-3.118%2C-60.017 with any routing engine).

I wonder if this is expected or if some roads going out of the city are missing a prolongation to the rest of the network?
