The daily dispatch. [volume] (Richmond [Va.]) 1850-1884, 1883-05-25

the roadway, which will be thrown open TO
the nubIic this week, consists OF a steel
framework as feet in width suspended
from the four cables by steel suspenders
attached 10 steel fioor-beams, seven and
one-half feet apart. six longitudinal trusses
divide the flooring into five parts. The
two outer parts are for the use OF vehicles.
The two inner divisions are laid with steel
rails ana provided with endless wire ropes
for hauling across the rnpld-transit
cars. Between the two inner divisions,
AMI at some distance above them, Is
the space devoted to ioot-passengers, iif-
teen feet seven inches In width, a pro-
mcnadc the most elveted and slightly that
the world has ever seen. At the Brooklyn
end Is the machinery which will move the
endless ropes and send the cars speeding
across the bridge in five minutes time.
The fare on the cars has been fixed at five
cents. The toll for ioot-passengers VIII be
one cent, while vehicles will be required
to pay toll varying but little from that
now exacted on the fcrry-boats. Twenty
four cars will be In operation in trans OF
four cars each. The cost OF this system OF
rapid transit will be hal; million dollars.
Although numerous accidents have oc-
CURED and many deaths have been noled
among those employed on this wonderiul
bridge, il is recorded as somewhat curious
fact that no break has occurred IN the engi-
neering staff since the death OF tne elder
Roebljng. Associated with Colonel lioeD-
ling from the very beginning OF the woik
were C.. G. Martin, Colonel w. II. Baine,
Francis Collngwood, George w. McNulty,
and s r. Probasco. civil engineers, and r..
+. Harrington, master mechanic. Inat these
1 a n ~. lt...r -
gentlemen share with Colonel Roebllng IN
no small dgree the honor OF its successful
completion is not doubted by the newspa-
per reporters, who, next TO the trustees,
have kept the most faithful watch over tnis
vast enterprise. One OF the latest decis-
ions OF the trustees was that OF llghtling
| the bridge by electricity, and ornamental
supports for the glass globes Of the electric
system were accordingly placed in position
for That purpose.
