I-84 East Exit 35 signs are all part of the Southington to Farmington project. This includes replacement of existing pipe gantries for the 1/2 mile and "exit now" Exit 35 assemblies. It also includes adding a 1/4 mile assembly. Also, I have yet to see replacement signs for the Exit 36 "exit now" and Exit 39A "exit now".
Westbound, at last check a month or so ago, the Exit 39 "exit now" sign was still mounted on the bridge, with its successor on a new monotube bridge in front. Recent traffic cam footage shows the Exit 36 1/2 mile overhead not replaced yet. As for Exit 33, the Route 9/72 sign replacement project will change out the exit tab to an EXIT 33 B-A instead, so that what is now 72WB Exit 2 will become Exit 33B. This would most likely be the equivalent to the eastbound direction, with the "33" being replaced with the mileage-based number, retaining the "A" and "B" suffixes.
