(Portland, OR)  --  More changes are coming to the Gateway Green Project.  It's located at the intersection of I-84 and I-205 in Northeast Portland.  The park already includes hiking trails and mountain biking.  The work is beginning at the south end of the park.  It'll include a new entry plaza, a thousand feet of new bike trails, a new trailhead, restoration of oak habitat and a five percent grade that will make it easier to access the park.  The third phase of the project is expected to be completed this fall.
