The Mount Holly news., 1917-11-20

WAS ldiu on Jl6 table.
Engineer Logan rendered report on
the condition of the bridges in the
county, as follows:
Bridges on improved roads and un-
improved roads over which motor
trucks may travel were measured pro-
viding their span exceeded 5 feet
This removes Immediately from con-
sideration all small bridges and Gull
verts and all the bridges in the pine
belt if unimproved roads.
This report will cover 378 bridges.
They are constructed either of timber
or metal. Of these, 206 are wooden
bridges, SO are wooden trestles, and
73 are metal bridges.
Of the 2O6 wooden bridges 8 can
carry load of 1914 tons, have been
repaired since inspection, 1852 can be
repaired so as to carry 12h ton
load, and 80 must be entirely or al
most entirely rebuilt.
Of the 80 wooden trestles, 6 can
carry a load of 1914 tons, 62 can be
repaired SO as to carry this load, and
81 must be entirely or almost en-
tirely rebuilt.
Of the 73 metal bridges, 9 can carry
load of 121s tons, 80 can be strength
ened so as to carry this load, Is can
be strengthened so as to carry load
of from to II tons, while IL are not
worth strengthening and should be
replaced when possible.
Table
20 bridges can carry load of 121z
tons.
a bridges have been repaired since
inspection.
256 can be brought up to 121s tons
Is can be brought up to from 8 to
II tons.
80 new structures required.
OF the 80 new structures required
II are on the highway in Bass River
township which is to be taken over
by the state al an early date, and
IL are county line bridges. The re-
naming 81 can sustain safe loads as
follows:
at tons, Is at tons, 5 at tons
IA at tons, at tons, A at 2 tons
2 at tons, at 9 tons, at 10 tons
2 at II tons.
Cost of Repairs
The following estimates are based
on the unit prices given below:
Yellow pine. $75 per M
Steel. .12c per lb. in place
Concrete. 500 per cubic yd. in place
Piles. $40 per pile in place
Wood block. -. $5 per SO. yd. in place
Painting (truss bridges);
So per lineal #
Painting (I-beam bridges),
81 per lineal #
Labor on wooden structures equal tC
cost of material.
The cost of bringing the 256 bridges
to 1914 tons and the Is bridges tt
from to II tons is estimated to be
$66, 10000.
Wood block pavement has been esti.
mated for 38 bridges at cost of $27,-
060.0O, which includes where necessary
the strengthening of the floor sys.
tenn. This cost distributed over three
years is an expenditure of 100000
per year. This pavement has beer
estimated for A bridges which nov
have a capacity of 1914 tons at cost
of $4,155.00. This item is included
in the $27, 100000 but not in the $685.,
10000.
Painting.
The cost of painting all of the
metal bridges is estimated as $7,2O5.
90. This should be distributed ovel
five years, that is, each bridge should
be painted every 5 years at an ex-
penditure of $1,44100 per year.
All the estimates concerning county
line bridges contain only the amount
to be paid by Burlington county.
A map has been made of Burling-
ton county. These bridges have been
numbered in their correct position or
same.
/ recommend that the Board consid
er very seriously the necessity O.
painting their steel bridges in rota
tion and thereby maintain them. Th'
amount necessary for this each yeal
is quite small and l wish to impress
upon you that the loss through fail
ure to properly paint them exceeds
this amount at least five times.
recommend that the bridges cap
able and of suitable floor system be
covered with wood blocks as rapidly
as your finances will permit, which
figure to be at the rate of $4,000 per
year for three years. If this policy is
followed it would certainly be very
wise for you to obtain bids for fur
nishing creosoted plank, mailing
pieces, wheel guards and blocks from
the various manufacturers. You
could advertise for bids for these ma
terials delivered within Burlington
county, giving the approximatea amount
you intend to purchase for the year.
! feel sure that this business would be
quite attractive to these people, es-
pecially the first or early part of each
year. AS you know, we have been us
ing wood blocks more and more each
year for floor systems and they are
meeting with approval by the travel
ing public and they are very satisfac-
tory. They should require no main
tenance for at least twelve years, pos
sibly longer.
If these two recommendations are
carried out, there will be an expendi-
ture of $1,000 per year for the next
three years and an expenditure of
81, 800 for painting for several years
to come.
feel that we will keep quite little
below the total estimate and allowance
of 81 900 for this work.
