This route travels through well-populated areas as well as through a long industrial estate and might be your only option following heavy rains. To follow this route keep on straight after the bridge. The arrows along the way are extremely faded but there are a few ceramic shells to keep you in the right direction. It is fairly straightforward: Keep on straight through a residential area full of bars and shops and play areas for children. Where this road ends turn right onto Calle José Payán (a narrow road). Follow it to the first large intersection, which is a roundabout known as Plaza Constitución and which is identifiable for the Iglesia de Santa María de Gracia. From the roundabout keep to the left (passing the church with it on your right) and continue all the way to a large roundabout.
NOTE: This is a large roundabout and you have to get to the other side without the benefit of any protection rails, so be careful and go slow. Once on the other side, the camino follows a straight path through an industrial estate (though along a dedicated bike & hike lane). At the far end of the estate, it rejoins the river route and proceeds into Santiponce.
