    The new light rail transit bridge will be the first bridge of its kind in the United States; it will include light rail, buses, bicyclists and pedestrians but no private automobiles. The new bridge will have a clear span of 860' (262m) over the Willamette River with a pair of elegant needle towers 180' (55m) in height. It combines both suspension and cable stayed technology making it both memorable and innovative. The new bridge will be self-anchored and will not require large anchor blocks at the shore lines. It is well suited to the existing context in relation to the adjacent Ross Island Bridge given its curved profile and the use of suspension cables. With its unique contemporary appearance and state of the art technology, it has a strong potential to become a new landmark for the City of Portland and the region.
