The work of the State Highway Department in Polk County during 1917 and
1918 has been confined chiefly to the design and the supervision of
construction of bridges. In addition to the design and supervision of
the Salem Bridge which is partly within Polk County, and which is
described in detail in an article in the chapter devoted to Marion
County, the Department has handled, at the request of the Polk County
Court, the following bridge work, all of which has been paid for by the
County.

built over a slough on the Mulkey Cut-off. This bridge complete cost
$1,898.17.

A 160 foot suspension foot-bridge was built over the Big Luckiamute
River at a cost of $500.00, to accommodate school children attending the
