I think the contractor just used a bad color on that LEFT plaque. It's always been a left only exit, regardless of the contruction activity in the area.
On the NB side, I like they added 'Capital Complex' to both signs. That said, they really didn't do much after you exit the highway to convey what to do or where to go; there's some limited signage but that's it. The right most 'Exit Only' isn't necessary because it's just a cloverleaf-type exit here where the on ramp enters the highway just about 150 feet before the lane exits (

Since you were in the area, I'll mention this as well: I wished they put this sign bridge *before* the overpass, not after where its visibility is severely limited:

The Left 3 Lanes plaque is annoying where its been used around the state, often when there's only 3 lanes in the area to begin with.
