(Olympia, WA)  --  Washington state lawmakers are introducing bipartisan legislation that would begin the process of replacing the Interstate 5 bridge between Vancouver and Portland.  Democratic Representative Sharon Wylie of Vancouver and Republican Senator Liz Pike of Camas have filed their respective bills.  They include a measure to facilitate "strong public participation" to identify the most affordable, efficient project that improves freight mobility and safety, relieves congestion, and meets the future needs of the region.  Both bills are under committee review.
