Hi, we've just come back end of August last weekend , going was fine , 5 minutes along river and back on route but coming back was not so quick , what should of been a few minutes on bridge ended up being stuck over an hour in gridlock traffic , i wish id turned off onto the HGV divrsion so keep your eyes open for it if you get stuck in it cos HGVs are banned in area whilst bridge shut . I've heard it's not going to be opened tii October to .
