The Hawthorne Bridge is the oldest operating [[wikipedia:Vertical-lift_bridge|vertical lift bridge]] in the United States. The Hawthorne Bridge was designed by renowned Kansas City engineering firm Waddell &amp;amp; Harrington and its steel superstructure was made by the Pennsylvania Steel Company. It &amp;#039;&amp;#039;&amp;#039;replaced&amp;#039;&amp;#039;&amp;#039; the wooden &amp;#039;&amp;#039;&amp;#039;Madison Street Bridge&amp;#039;&amp;#039;&amp;#039;, opening to pedestrians, horses, vehicles, and street cars in late 1910 as just the third major vertical lift bridge in the country. Like &amp;#039;&amp;#039;&amp;#039;many landmarks&amp;#039;&amp;#039;&amp;#039; around Portland, the bridge takes its name from 19th-century physician James C. Hawthorne.&lt;br /&gt;
&lt;br /&gt;
Today, the Hawthorne still largely relies on its original operating system, plus electrical power and controls installed in 1975. Those were updated in 1999 during a project that also widened the bridge’s sidewalks and strengthened the deck.&lt;br /&gt;
