<br />Attachment A - Corridor Congestion Summary <br /> <br />Hiahwav 99 <br /> <br />This roadway carries a relatively minor percentage of the mobility dependent trips of the <br />TMA in four of the five sub-corridors. The Washington/Jefferson Bridge to Garfield sub- <br />corridor carries levels of mobility dependent trips similar to those seen on 1-105 and <br />Beltline. <br /> <br />The OHP mobility standard for this highway is 0.85 to the Eugene Urban Growth <br />Boundary and 0.70 north of that point. <br /> <br />2002: <br />All of the sub-corridors meet the standard based on the average peak period VMT <br />weighted V/C within each sub-corridor. <br /> <br />In the PM, there is a congested segment in the northbound traffic flow between Garfield <br />and Elmira Rd with V/C approaching 1, and for southbound/eastbound traffic at Garfield <br />St. with V/C at 0.96. <br /> <br />2025: <br />In the RTP- Financially Constrained scenario, the Washington/Jefferson Bridge to <br />Garfield sub-corridor slightly exceeds the OHP standard in the northbound direction with <br />a portion of the sub-corridor reaching 1.05. This sub-corridor fails because of high PM <br />flows throughout the length of the sub-corridor - Washington/Jefferson Bridge through <br />to Roosevelt. <br /> <br />Further, there are segments of the sub-corridors between Airport Road and <br />Washington/Jefferson Bridge northbound/westbound and Roosevelt to Washington/ <br />Jefferson Bridge southbound that fail the standard. Most of these are due to <br />interchange interactions - Beltline at Hwy 99 northbound in the PM, 1-105 at W.7th in the <br />AM and PM, and also W.7th at Garfield in the AM and PM, at 5th Place in the AM. <br /> <br />The table below summarizes the V/C results for the AM and PM periods of the 2025 <br />RTP- Financially Constrained scenario, noting where the sub-corridor meets the <br />performance standard (~) and also where a segment within that passing corridor may fail <br />(*) . <br /> <br />Sub-corridor AM AM PM PM <br /> Northbound Southbound Northbound Southbound <br />1.
