Bow Flyover last night

I got to MacD’s under at the Bow Flyover labout 5:30 last night to find lots of police, Bow Road shut and the slip road taped off - grateful to the bike copper who pointed me out and waved me through to go over the flyover whilst stopping all the cars! Interesting detour home via Stratford and Leytonstone, almost doubled my journey time back to Chelmsford.
