Brian Dorling, 58, and Svitlana Tereschenko, 34, were killed in separate crashes on the painted blue Cycle Superhighway 2 (CS2) at Bow Roundabout in November 2011.
It is thought the latest cyclist to be killed had been cycling on the CS2, although the crash happened just off the cycle superhighway.
Crappy infrastructure is often less safe than no infrastructure.
