The Thames Super Sewer project work is now affecting the Thames Path around Vauxhall.
After Lambeth Bridge, the path follows the Albert Embankment where the road gradually leaves the riverside allowing the path to be separated from traffic by welcome grass.
However, where the path once went ahead between a building and the water there is now a diversion. Don’t go through the temporary barrier even if it is open – you won’t get far.
Turn inland by the building (number 93) to follow the Albert Embankment main road.
But a few yards beyond Cafe 89 (right) turn right into Lack’s Dock to return to the river and follow an enclosed path along the back (riverside) of the MI6 Vauxhall Cross building.
The tunnel under Vauxhall Bridge is now closed so climb the steps and go left to use the road crossing. On the far side of the bridge approach turn right and soon find a path on the left running down to the Thames Path on St George Wharf.
There is a further diversion a little further on at Nine Elms.
This is at Bourne Valley Wharf where the proposed Pimlico footbridge may land.
From here one must go inland and cross the Nine Elms Lane main road. At once turn right to continue upstream.
This may seem a long way from the river but there is a good view of the moat being dug for the new US Embassy.
Soon after Waitrose it is possible to go back to the opposite side of the main road by using a pedestrian crossing and return to the river by passing between tall buildings.
Tuesday 1 August is Lammas Day when when the first wheat from the harvest is made into a loaf to be the bread consecrated with the wine at a thanksgiving Mass.
Lammas comes from an Anglo Saxon word meaning loaf mass. The ancient custom predates the autumn harvest festival.
There will be the blessing of bread in Borough Market followed by a procession to nearby Southwark Cathedral where the bread will be offered at Mass and consecrated as the Body of Christ.
The Blessing of bread is at Bread Ahead in Cathedral Street at 12.15pm.
Upstream at Cricklade in Wiltshire the hay has been cut on North Meadow where Lammas Day marks the start of grazing. However, the town still observes the old calendar so the gate will not be opened until Old Lammas Day on 12 August.
This later date was when harvest was more likely to have started but this year walkers will find harvest already under way all along the river.
Staines-on-Thames recreation ground is Lammas land where the barons gathered in 1215 before meeting King John on Runnymede to secure Magna Carta.
