The northbound Blackwall Tunnel is a traffic bottleneck with tailbacks. Traffic jams or tailbacks of have been reported.

The heavy usage, particularly during rush hours, can lead to significant congestion and tailbacks. The protest caused rush-hour tailbacks on both sides of the bridge. There is often congestion with tailbacks at the weekends, especially on Sunday evenings. Jennings, who split time with two other tailbacks, was not heavily recruited by college programs. In 2013, he joined the Western Kentucky football program as tailbacks coach. This caused tailbacks on the approach to the airfield.
