History
The Big I was originally built in the mid 1960s with left exits designed to handle 60,000 vehicles per day. By the late 1990s, however, it could no longer handle Albuquerque's increasing traffic flows and needed to be replaced. Construction work on a new interchange began in June 2000 and lasted until May 2002.
The reconstruction, which was budgeted to cost $221.8 million (equivalent to $ million in ),
was completed at a total cost $293 million, (equivalent to $ million in ), and took 23 months to complete. The reconstruction was the largest public works project ever undertaken in New Mexico, and was the winner of the 2002 President's Transportation Award for Highways from the

A survey done in 2002 showed that after the completion of the project, the hours of annual delay dropped from 16 million to just 1.1 million.

next to the interchange.
It was first erected in 1995 by the Albuquerque Metropolitan Arroyo Flood Control Authority (AMAFCA) and has been an annual tradition to put one up every December.
It is built from three tumbleweeds and recycled material accessories. It starts on "Tumbleweed Tuesday" which is the Tuesday following Thanksgiving. By August, AMAFCA employees start to look for tumbleweeds they can use for their snowman. They weld their 3 tumbleweeds together on a stand to protect it from windstorms, and the snowman stands tall until the first week of January. The AMAFCA hat they use for this snowman is a 55 Gallon steel pot. The scarf around the snowman is made by one of the construction employees mother in-law.
