View across Mersea Fleet. In the background at right the Strood causeway can be seen. It was first constructed in Roman times and presently is part of the B1025 that connects Mersea with Colchester. The causeway can become flooded during high tides; during particularly high tides the bridge is impassable by vehicles including the emergency services, except for those with high clearance, for over an hour. Mersea Island, located off the coast to the SE of Colchester, is the most easterly inhabited island in Great Britain.
The Strood causeway flooded at spring tide. The picture shows the causeway to Mersea Island, from the island. The Strood has been in use since the Roman occupation and regularly floods during spring tides. The vehicle shown was the last to go across. Subsequent vehicles turned back and had to wait for the tide to turn. Islanders rely on tide tables to plan their forays to the mainland.
