The southbound on-ramp and northbound off-ramp, along with <br />Full Interchange: <br />the removal of the Hwy 99 ramps, could be constructed as a future <br />Diamond 2 <br />* <br />phase. <br />Full Interchange: <br />Partial Cloverleaf <br />2Partial Interchange: Partial interchange - no phasing considered <br />Partial Diamond <br />Partial Interchange: <br />Partial Cloverleaf <br />3 <br />Split Interchange: Two As with the Category 1 concepts, the ramps north of Franklin could be <br />½ Diamonds constructed first. The interchange improvements at Glenwood would <br />* <br />require reconstructing existing ramps with movements that already exist. <br />Split Interchange: <br />Connected Diamonds With the Connected Diamonds concept, a third phase of constructing the <br />collector/distributor roads between Franklin and Glenwood would be an <br />option.* <br />4Glenwood Interchange This concept could be constructed in phases, with the construction of a <br />Diamond new overpass and new southbound off-ramp and northbound on-ramps <br />constructed in the first phase, followed by the remaining ramps in a <br />* <br />second phase. <br />* <br /> This assumes that the proposed phase would have independent utility under federal regulations. <br />PDX\052200014 7 <br /> <br />
