Los POSOS GETS
MODERN BRIDGE
CITY AROUSED BY RECENT
DEATH DIP HORROR
Engineering Department Submits Re-
ports on Macy, State and Ma
renao Vsduots Which VIII
Be Built Shortly

Following the dip of death" accident
on the Brooklyn avenue car at the
Arroyo de los Pesos the city authorities
have taken action regarding a new
bridge.
The trolley officials have already ar
ranged to buy nearby ground in order
to do away with the tortuous curve at
that point which makes transportation
dangerous. The bridge Is another step
| in the direction of safety of travel. The
| city is to share the latter expense with
| the railway company.
The city engineer has also forwarded
reports to the board of public works
on the State street and Marengo street
bridges and the three recommendations
will be carried out at once having re-
ceived sanction from the higher pow
| ers.
Here are the reports summarized:
Wants Concrete PedestaIs
"Concerning the Macy street bridge
over the Arroyo de los Pesos 1 recon-
mend the approval of the proposed
change in substructures, except would
substitute concrete pedestals under
each post for the 4 foot by 10 inch by
10 inch timbers shown. The cost will
be about the same"
Regarding the State street bridge ne
says:
II recommend that the type of bents
be altered to conform to the type pro-
posed for Marengo street and that in
stead of timber bulkheads concrete
abutments be CONSTRUCTED with foot
ings under the present surface of the
ground. The fill at the south end OF
the bridge will. rest against the front
of soap factory building. The rail-
way company should, of course, fill the
approaches and pay all damages"
| Regarding Marengo street bridge
Engineer Hamlin's report states:
ITO avoid the possibility of a grade
crossing the railway company proposes
| to construct a frame treStle bridge
1927 feet long, with floor high enough
| to give their standard clearance or 22
| feet from top of rail.
eff the city Is to maintain the struc-
ture it should be made as short as
practicable.
Increases Expense
"The length can be decreased 81 feet
by constructing concrete abutments to
the level of the joists at bents num-
bered 4 and II. The plan would in
crease the expense to the railway COM
pany by $3500, a rough estimate. A
cheaper plan which would decrease the
length by 10 feet would De to end the
bridge at bents and II and construct
at bents and 16 retaining walls suf-
ficiently high to catch the slope of the
fill at an additional cost Of about $780,
at consider the plan of rest
| ing the end of the joists on mud
sills and Of allowing the posts of the
| first bent to penetrate the fill to be un-
desirable.
"The grade of the approaches can be
reduced and the appearance of the
street improved by reducing the clear
a. fan no N W n c q
only 20 feet at the State street bridge.
1 would recommend that the length be
decreased 70 feet, the floor lowered 2
feet and the roadway paved with as
phalt with a five-year guarantee OF
pavement; also that certain changes
in detail be made.
City Makes Safeguards
"Your attention IS called to the fact
that no foot walk is provided, though
none is needed at the present time.
Also. that provision should be made
for filling the approaches by the rail-
way company or otherwise so that the
bridge can be used as soon as COM
pleted.
eff the recommendations as to end
walls and grades be adopted I sug-
geSt that the railway company be
asked to send revised plans to this
department for approval.
"I have estimated the cost of more
substantial frame trestie bridge with
sidewalks and concrete abutments at
the Los Angeles Interurban railway
crossing at Marengo street as follows:
Length of bridge 1855 feet; width Of
roadway, paved with asphalt, % feet;
,, two sidewalks, each 5k feet; face of
concrete abutments, S.5 feet from CEN
ter of track; vertical clearance, 80 feet.
"(Fill of approaches not included)
Cost of superstructure 1855 feet
lin. feet at $40. 0.40.............$ 2,449
Frame bents ................... 1,464
Two abutments and wings. 6,Os6
$4,000
