SUBJECT: Bridge Drive Bridge, E-197-1
At the request of Larry Rice, Tom and myself inspected the
Bridge Drive Bridge that crosses the Little Deschutes River in
the Lazy River South Special Road District. This bridge is due
for replacement in the winter of 1989 with special bridge
replacement funds.
We found the following during the field inspection:
1. The bridge is a timber structure sixty-two feet in
length and twenty-four feet in width;
2. The substructure and superstructure does not meet
current standards and is the primary reason the bridge
is being replaced;
3. The deck is a single layer of transverse 4" X 1211's
which were replaced about five years ago;
4. On the north side of the bridge, the deck continues on
about 3.5 feet past the last supporting stringer;
5. The guardrail has completely failed on the south side
and on the north side the rail is inadequate to the
point it is a hazard;
I recommend that the Public Works Department take the following
action in regards to this bridge:
Post a weight limit sign of 9 tons. This is the
operating rating loading shown on the State STRUCTURAL
Inventory and appraisal form. A weight limit will
require an order from the Board of Commissioners
before it can be posted;
0
2. Install a type 2A guardrail and approach rail. This
would require three feet of the cantilevered deck to
be removed;
3. Consideration should be given to placing another deck
on for wearing purposes and better distribution of the
load;
4. If the above work is completed, the following
additional signing will be required;
a) Weight limit signs on the bridge;
b) An advance weight limit sign at the intersection
of Riverview Drive and Otter Drive;
c) Narrow bridge signs on the approach roads;
I would be happy to discuss these recommendations with you at
your convenience.
