This IMO is a clear cut case for a interchange split between Convention Center Blvd & South 5th Street. Fairgrounds Road has a full set of ramps with I-70 serving all movements, while South 5th Street is missing the WB I-70 onramp (uses North Outer Road to connect to Convention Center Blvd's ramp for that movement now).
This is due to them adding the new 229A interchange @ Convention Center Blvd, which opened sometime between
Jul '16 &
Dec '16.
Would recommend the following changes here:
NEW -> 229A (@ Convention Center Blvd)
229 -> 229B +229
