(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.
