Notes – ID 305 (I-5 SB): Since opening, the NB portion of this segment was converted from 2+ to general purpose.  ID 308 (I-5 SB): Converted from 3+ to 2+ in 1991.  The northernmost segment of the HOV lane originally operated as the outside lane, was later moved to the inside lane.  ID 309 (I-5 NB): Converted from 3+ to 2+ in 1991.  IDs 310, 311, 316, & 317 (I-405 SB, I-405 NB): Most of these HOV facilities originally operated as the outside lane, was later moved to the inside lane.  IDs 312 & 315 (I-5 SB, I-5 NB): Converted from 3+ to 2+ in 1991.  IDs 313 & 314 (I-5 SB, I-5 NB): Portions operated as 3+ until 1991-92, then were converted to 2+.  IDs 318, 319, & 320 (SR 520 EB, SR 520 WB): The HOV lanes will be moved from the outside lane to the inside lane to match the rest of the system once the SR 520 bridge is replaced.  ID 320 (SR 520 WB): This segment originally was open to transit vehicles only, then opened to 3+ HOV.  IDs 323 & 324 (I-90 EB, I-90 WB): HOV facilities were shortened by about 1 mile after original operations.
