closed for 14 days on end in December 1931) but labour concentra
ted at the vital points should be able to affect a clearance in three
days.
In April and Mav when the snow melts the road is liable to
be considerably damaged by flood water, though the likelihood of
interruption from this cause has been lessened by the substitution
of stone or concrete bridges and culverts for the wooden ones.
Picks and shovels should be carried by all vehicles and every JVb l.
convoy should carry beams of 6 inches diameter and 10 feet lengt i
for making ramps or repairing culverts and road subsidences oi to
shore up weak portions. Chains should be carried by all vehicles
to cope with snow or mud.
6. Exceptional Features. —(a) Rivers. The chief rivers met
with are:—
(i) the NIMRUD at mile 483;
(ii) the RUD-I-HIND at mile 535 ;
(iii) the JAJARUD at mile 549.
All of which are adequately bridged.
(b) Passes .—There are five notable ascents, viz. :
(i) The pass at mile 412%.
(ii) The BASHM pass at mile 458|.
(iii) The 7 mile ascent from the NIMRUD river mile
4821—489|.
(iv) The 3 mile ascent from DILICHAI, mile 498|—501i
(v) The 4 mile ascent from the JAJARUD, mile 549 553.
These are all graded but they are long and steep and prove
a serious obstacle to much of the civilian M. T. overloaded and
overdriven by Iranians.
(c) Bridges .—The bridges are, on the whole, strong and well
made up to heavy M. T and are daily used by 7 ton lorries with-
out visible signs of damage.
(d) Fords —These are numerous in the two plain portions
and consist of Irish bridges unpaved across irrigation cuts and
stony nullahs dry in summer but liable to become blocked by mud
or boulders brought down by the water in spring. _
(e) Tunnels .—There is only one tunnel in this section at
mile 502. It is strongly constructed and its dimensions will permit
the transit of the largest M. T. with ease.
7 Repair Facilities —Unlimited quantities of stone and
shingle are available throughout the length of ,
steam rollers were seen until within P miles of TEHRAN where
two were working (August 1933).
