For the whole replacement project, particularly around the 91 interchange, they've made no attempt to update the signs to reflect lane reconstruction that has occurred since the original button copy signs that are now being replaced were first installed.
For example, in the portion of the interchange depicted in the above picture, about 20 years ago a second transition lane was added for the movement to the 91 north. It is visible on the far right of the picture.
For the northbound 605 to 91 interchange, an option lane for the 91 west was removed and the freeway was restriped to have dedicated exit lanes to the eastbound and westbound 91, yet the signage was not updated then or now to reflect these "Exit Only" lanes.
For the southbound 605 to 91 interchange, an option lane for the 91 east movement was added many years ago, yet the approach signs were never changed to reflect this option lane, and the replacement signs ape the old, incorrect signage that was there.
The worst part about this is that almost all of the prior button copy signs in this area were installed in the 90's as part of the conclusion of the 105 interchange construction. They were in excellent condition. So if District 7 wasn't even going to update the signs to reflect the various changes to the roadway, there was hardly a reason to replace the existing button copy.
