For some centuries, commercial trade through the port was limited in part by the shallow waters on the approach to the quay, but mainly by the power of Exeter, which owned the dock and controlled all estuary traffic. The roads in and out of the area were in a poor state and only occasionally repaired by the parishes through which they ran. A more permanent dock was built in 1825, replacing a series of apparently seasonal docks first noted on maps from 1576 as "The Docke". New docks designed by Eugenius Birch were opened in 1868, and a short line connected them to the railway goods yard. The area adjacent to the docks once housed a thriving community of some 125 chalets built on the shoreline. These have been replaced by a residential marina complex known as Exmouth Quay.
