on the north side of the street. The recommended improvement would widen Alton Avenue on the south side of the street to provide four travel lanes with a central turn lane or median including the turn lanes at the intersections with Raitt Street and Bear Street. The Alton Avenue widening would begin at Raitt Street and end at Bear Street. The existing right-of-way within this section of roadway is approximately 52 feet. This improvement will require an additional right-of-way of approximately 26 feet on the south side of the street. These rights-of-way are recommended to be provided by the project. Overall, this improvement would include 13-foot curb lanes, 11-foot through lanes and a 10-foot central-turn lane, as well as an 8-foot parkway/sidewalk area on the south side of the street. All construction would occur on the south side of the street. TR-9 MacArthur Boulevard Currently, MacArthur Boulevard between Raitt Street and Bear Street contains five travel lanes - two lanes in the westbound direction and three in the eastbound direction and a raised median with a sidewalk on the south side of the street. The existing right-of-way along this roadway segment between Raitt Street and Bear Street is approximately 90 feet. The recommended improvement provides a third continuous westbound travel lane between Bear Street and Raitt Street, as well as a sidewalk/parkway on the north side of the street within that stretch. A 60- foot-wide half-roadway (centerline to north right-of-way line) to accommodate three westbound through lanes, a landscaped median/turn lane and a 10-foot-wide sidewalk on the north side of the street is recommended. In other words, an additional 22-foot right-of-way would be needed on the north side of the street, except at the Raitt Street intersection. From approximately 290 feet east of Raitt Street to the intersection at Raitt Street, the right-of-way requirement would be approximately 28-feet on the north side of the street to allow for provision of a 200- foot-long, 12-foot-wide westbound to northbound right turn lane plus a 90-foot-long turn bay taper. These rights-of-way are to be provided by the project. Overall, this improvement would include a 13-foot eastbound curb lane, 19-foot westbound curb lane, 12-foot through lanes and a 14-foot raised median with turn lanes at intersections, as well as a lO-foot sidewalk on the north side of the street. Improvements the project would be required to make a fair share contribution to:
