The entry to the Circle has brick that matched the original Martin Hall. I don't think they will be changing that any time soon given the historical significance of the entry.
I just finished a foundation design for a long circular wall that will be near the flag pole. It will be about 80 feet long and will be concentric with the circular drive. It will be decorative on the side that faces Martin Hall and will have University of Louisiana with at Lafayette in small letters on it. It will be high enough to block the parking lot in front of Martin Hall so that if you want to take a photograph of people in front (the side facing the inside of the circle) of the wall they will have Martin Hall in the background with the parking lot blocked by the wall. There will be an alternate bid that will include flag poles on one side and another lower decorative wall on the other.
I just finished a survey of the area between Moody Hall and the Presidents home starting at the Martin Hall Parking lot and extending across Hebrard Blvd down Boucher to McKinley. This will be for the next phase of the walk of honor. It was mentioned on page 10 and 11 of the latest issue of LaLouisiane. They won't start on that until the Student Union is finished.
It is my understanding that they will place the new statue of Dr. Stephens in the new plaza area around Girard hall at the University/Johnston intersection. I don't know that for sure though.
