a Public Road under the Thames. 69 
a height as to admit vessels to pass under it at prin: tides, pith 
out lowering their masts. 
These repéated attempts to obtain a road-way for passengers and 
carriages eastward of London Bridge, across the river, together 
with the almost impassable state of London Bridge, from the 
crowds on it, in the middle of the day, show that there is a demand 
for such a communication between the sides of the Thames, east= 
ward of London Bridge. The questions to be considered, are, First, 
what method of obtaining such an object is the best? Secondly, 
how that method can be carried into effect with certainty? Thirdly, 
what is the best site for sucha road-way? Fourthly, whether such 
a work, in the site hereby laid down, would not be of such political 
importance, facilitated as the execution thereof would be by a 
possession of the ground necessary for the northern approach, as 
to warrant the State in undertaking the work, leaving to the public 
the use, subject to certain tolls and restrictions, as may accord 
with the uses of it by Government? Fifthly, as to time, should 
the cofferdams necessary to resist the deep water in the erection of 
the new London Bridge be of such a size as to cause an impetus to 
the river, or alteration of the mid-stream, so as to destroy the pre- 
sent bridge, or render it impassable, (it being intended that it shall 
remain until the new one is passable), would not then such a way 
as the one hereby proposed be a great relief to Southwark 
Bridge, until a temporary bridge be supplied? And, comparing 
generally the expediency and cost of carrying into effect this design 
with the expediency and cost of rebuilding London Bridge *, ought 
not this work to have the precedence ?
