Pecuniary Advantages. 
A small part of such a revenuet, as would be derived from the 
number of passengers and carriages which has been estimated to 
pass London Bridge daily, calculated at the tolls allowed to the 
Southwark Bridge Company, would be ample to compensate the 
cost of this arch-way. 
The taxes arising out of the materials of the buildings likely to: 
be erected, together with the assessed taxes arising out of them 
when built, in the ways to and through the lower road to Deptford, 
and in communicating with the Kent Road, consequent on such a 
connexion between the two sides of the Thames, would be a great 
source of revenue to the government, probably more than sufficient 
to compensate the cost of this arch-way. 
* This mode of approach is also applicable to a road descending from a 
bridge ; is cheap, by lessening the expense of compensation for the buildings 
and ground required and damaged in making an inclined plane ; and is con- 
venient, because the foot of the inclined plane is at the river.
