The La Concha lobby is spending the winter in an outdoor gallery called the Neon Museum's "boneyard," a three-acre site where the museum stores neon signs it salvages from demolished motels.

In an engineering study funded by the National Trust, Melvyn Green and Associates determined that the building could be safely cut and moved and reassembled.

So the building's owner, the Doumani family, who commissioned Williams to build the motel, donated the lobby to the local Neon Museum and allowed the group time to gather state grants and donations for the project.

So far, the museum has raised $990,000, and the move cost $400,000. Workers had to cut the concrete structure into eight parts so it could be moved beneath a freeway overpass.

"The move was more costly than anticipated because, since this had never been done before (cutting a thin-shell poured concrete structure of this size), the contractor was very cautious and added extra shoring and bracing," Dorothy Wright, museum board member, said in an e-mail.
