- This configuration eliminates the weave along SB SR 896

develops the SB I-95 to SB SR 896 ramp as the second through lane on SB SR 896

- Requires converting the left through lane on SB SR 896 to a left turn lane and

- A new signal would be installed along SR 896 (LOS F)

from NB I-95 to NB SR 896

- A phase could be added to the signal to provide time for the left turn

the NB SR 896 to SB I-95 left turn

- Queue length on SB SR 896 would be approximately 1,260 feet, possibly blocking

approximately 4,090 pc/h during the 2015 AM peak

- The combined volumes on the NB I-95 on-ramp from SB and NB SR 896 is

than 2,250 to 2,400 pc/h through a merge
