The 473 travels through Plaistow to Stratford and the 474 travels towards Central London finishing at Canning Town where travellers can transfer to another bus or pick up the Underground to continue further into the city.

Time: Depends on your destination and traffic.
Cost: Fare are £1 on a prepaid Oyster card or £1.50 paid in cash.
