                   Currently there are two southbound lanes in the first block
                   of 5th Ave. but only one of those two lanes (the southern) is
                   useable due to restrictions on turning movements. The con-
                   cept proposes removal of the unused lane and expand-
                   ing the sidewalk and curb bulb area. This allows for an ex-
                   panded greenspace and streetscape zone for synergy with
                   Tilikum Place Park. This also greatly reduces the east-west
                   crossing distance for pedestrians along Denny Way. The
                   added bulbs can also help to ‘meter’ traffic flow onto 5th Ave.
