To reduce congestion and improve operation, it is proposed to construct a connector referred to as a ‘flyover’ from southbound (SB) State Route (SR) 221 to SB SR 29 and modify the existing Soscol Ferry Road intersection.
Alternative 5, Option 1
Option 1 proposes to construct a 1.1-mile two-lane flyover from SB SR 221 to SB SR 29, and re-align the SB SR 221 connection to SR 29 at the existing Soscol Ferry Road intersection. The leg of SB SR 221 at the intersection would be reduced from three lanes (two left-turn lanes and one combined through and right-turn lane) to two lanes (one through lane and one right-turn lane).
Alternative 5, Option 2
Option 2 proposes to construct a 1.1-mile two-lane flyover from SB SR 221 to SB SR 29 and a single lane at grade connector from SB SR 221 to northbound SR 29 in Napa County. The leg of SR 221 and the existing signal at the Soscol Ferry Road intersection would be removed. The SR 29 median at the intersection would be closed.
