A number of National Cycle Network routes run through the region, including National Cycle Route 1. Provision for cyclists is good in some of the major towns within the region with Cambridge having the highest level of cycle use in the UK with between 18% and 25% of residents travelling to work by bicycle and nearly 50% of residents cycling at least once a week - the highest figure of any town or city in the UK - in a Sport England survey published in 2012. The Port of Felixstowe is the busiest container port in the United Kingdom and is a key gateway for container traffic into the country dealing with over 40% of container traffic. The port is operated by Hutchison Ports, a subsidiary of Hutchison Whampoa, and employs over 2500 people as of 2013.

Other significant ports in the region include Ipswich docks, the Port of Lowestoft, Great Yarmouth Outer Harbour, King's Lynn Docks and Wisbech Port. Ipswich deals with more than two million tonnes of cargo a year and has freight rail links on site. King's Lynn and Wisbeach are focussed on dealing with agricultural products from the surrounding farmland, whilst Lowestoft and Great Yarmouth play an important role in servicing the North Sea energy industries, including the growing offshore wind energy industry. A number of smaller ports and leisure harbours, such as at Wells-next-the-Sea and Southwold operate around the region's coast. The major freight and passenger port of Harwich International Port is located just to the south of Felixstowe in Essex. Ferry services run from here to Esbjerg in Denmark and Hoek van Holland. Within the region a number of local vehicle and passenger ferry services remain in service, including the Reedham Ferry across the River Yare in Norfolk and the King's Lynn passenger ferry across the River Great Ouse.
