A406 North Circular, Near Middlesex Hospital , East Bound.

Just as you pass the hospital, when driving EAST BOUND on the A406, there is a bridge.

For 2 days now, I have noticed 3 black blobs of oil / diesel there under the bridge.

Thought it may be just water, but it’s pure black in colour …

Its in Lane 2 of 2 …

Watch out !
