TFL Easter roads advisory

[Ruskin]

From TFL's Easter Roads section:

"South London area ? On Sunday, from 08:00 until 12:00, an abnormal load will travel under police escort from the M23, via the A23 and the A205 South Circular Road to the Herne Hill area. During this time roads in the vicinity may be busy."

Anyone know what this might be? Not a bridge, surely!

New railway bridge for half moon lane?

If that's the case, I'd be interested to know its route from the A205. Turn right at DC into the Village or via the Norwood Road and under the existing HH bridge?
