At Bow Road, the junction with the A11 involves a triple-layer junction, Bow Interchange. The ECR passes through in a cutting below an interchange roundabout whilst the A11 passes above on a flyover. South of this junction, the ECR passes Bromley-by-Bow station and skirts the River Lee Navigation for a short distance as it follows the line of the former St Leonard Street. It then crosses Limehouse Cut and continues along what was Brunswick Road to East India Dock Road (A13). It passes under the A13 in another grade separated junction, becoming the A102, and then enters the Blackwall tunnel.
