In 1987, the Morrison Bridge became the first bridge illuminated by the Willamette Light Brigade.<ref name=wood-wortman/> In 2007, the original 16 colored floodlamps illuminating the concrete piers were replaced by energy-efficient and computer-controlled [[Light-emitting diode|LED]]s.<ref>{{Cite news |first=Susan |last=Green |title = Morrison Bridge will get its lights back |newspaper=The Oregonian |date=February 14, 2007 |page= B2}}</ref> Different colors may be selected for each of eight zones of the piers.<ref>{{Cite web

Access for bicycles and pedestrians was improved in a $1.9 million project which began construction in March 2009 and added a barrier-separated path on the south side.<ref>{{Cite news |first=Nikole |last=Hannah-Jones |title=Morrison Bridge path construction starts today |newspaper=[[The Oregonian]] |date=March 26, 2009 |url=http://www.oregonlive.com/portland/index.ssf/2009/03/morrison_bridge_path_construct.html |access-date=August 6, 2012}}</ref> Previously, there were only narrow sidewalks.
