Umpqua River Bridge One Mile North of Dillard
This bridge consists of 3-144 foot covered wooden Howe Truss spans on
concrete piers. The spans are continuous, thus forming a roof over 430
feet long. Open windows are constructed at panel points to light the
spans and make a more artistic appearance, lack of light and unsightly
appearance having been the chief objections to covered wooden bridges.
This bridge being on the Pacific Highway, was designed for heavy traffic
loading. A laminated wood floor system is used and provision is made for
an asphaltic wearing surface although a three inch wooden decking is
used temporarily.
This type of bridge is regarded as being very durable, and under
conditions of the past year or two, very economical. The structure
complete will cost approximately $26,500.00. Mr. A. S. Kennedy was
resident engineer for this bridge as well as the one two and one-half
miles south of Dillard. The construction is being handled by the
Portland Bridge Company.

COUNTY. BUILT IN 1918]
Bridge Two and One-half Miles South of Dillard
This bridge is similar to the one described above, except that there are
two 144-foot spans instead of three. The cost of construction will be
approximately $19,000.00. It is being built under a contract with the
Portland Bridge Company.
Van Tyne Creek Bridge
This is a 60-foot reinforced concrete viaduct on the Pacific Highway
near Dole, north of Myrtle Creek. It was constructed by the Grants Pass
Construction Company, under their grading contract for the section
between Myrtle Creek and Dillard. The total cost of the structure was
$3,575.70.
Half Viaducts North of Myrtle Creek
These structures, two in number, were constructed within a few hundred
feet of each other on the Pacific Highway between Myrtle Creek and
Dillard and span crevices in the face of a rock bluff. They are of
reinforced concrete construction of the through girder type and of spans
of 45 feet and 58 feet respectively. The 45 foot structure cost complete
$2,415.28, and the 58 foot structure cost $2,648.54. Both were built by
the Grants Pass Construction Company under their contract for grading
between Myrtle Creek and Dillard.
Myrtle Creek Bridge
The bridge over the Umpqua River at Myrtle Creek being inadequate for
modern traffic a survey has been made for a new structure. As
contemplated, the new bridge will eliminate a grade crossing that now
exists at one end of the present bridge.
