Suburban Streets and Roads.
Large appropriations were made for
expenditure during the year in extend
ing the trunk highway lines outward
from the city. among them being the
following: 4..
Massachusetts avenue northwest. Nsbras. $50,
ka avenue to the District line -. t4o'Uo

Upsal street .............. iA'oov
In these and other, county roads and
suburban streets for which approprta-
tons were made there were constructed
1851 square yards Of cement roadway.
$3.50 square yards of macadam roads
and 1925 square yards OF paved gutter.
The grading done In connection with
this work aggregated 18S.3S0 cubic
yards.
In repairs to suburban roads the main
tenance of trunk lines of travel re-
Quired the greater part of the appro-
priation. Twenty-Five thousand dollars
was expended in maintaining eight Of
the more Important roads in fair condi-
ton. This amount does not include the
cost of oiling, which on all roads was
approximately S21,500. The winter was
unusually wet, and the repairs necss-
than usual. The appropriation was un-
equal to the demands made upon It.
and as a result many of the roadways
remained In poor condition. The In
creased cost Of labor and material was
also the cause of q less amount OF work
being done. 1t 10 believed that. due to
the causes above stated. the great in
crease In traffic and the increasing area
the appropriation for the construction
and repair of county roads should be
considerably increased. ~
