A section of path upstream of Blackfriars Bridge is being closed after 8pm most nights for the next few weeks.
This is between Marigold Alley and Oxo Tower Wharf to allow for scaffolding to be erected in front of Sea Containers House which is being converted into an hotel.
Signs are going up but the easiest alternative is:
Turn inland at Marigold Alley, go right into Upper Ground and on reaching a bus stop turn right into Bernie Spain Garden to rejoin the river.
