Brick 66
Auburn, Illinois
In one of the cruel ironies that vex Route 66 purists, the treasured 1.5-mile-long section of rural Route 66 now known as "Brick 66" was never actually part of Route 66.
Well, it was and it wasn't.
The stretch of highway was part of the Mother Road from 1926 to 1930. But the brick wasn't added to the roadbed until a year later -- after Route 66 had been routed to the less-trafficked east side of Springfield. The brick road was Illinois Highway 4, not Route 66.
But don't break the hearts of Mother Roaders you may meet on Brick 66. If they want to imagine that this stretch of Route 66 was once paved in brick, let them.
