My mom and I started our Route 66 drive this weekend with the section from El Reno, OK to Adrian, TX.
As a civil engineer, the bridges were probably my favorite part, but there were some other interesting civil engineering aspects also.
Originally built in 1934, Bridgeport Bridge was modified a couple years ago to make the bridge deck wide enough to accommodate modern traffic, but the original trusses were reused to maintain the original bridge as much as possible.

The Route 66 centennial is approaching quickly, and ASCE recently approved designating Route 66 as a National Historic Civil Engineering Landmark.
Nicknamed "The Mother Road," Route 66 starts in Chicago and goes through eight states before it arrives in Santa Monica. It has unquestionably made a cultural and economic impact over the years, and it attracts visitors from around the world. I'm curious to know how it has impacted members of the ASCE community.
Do you have any memories connected to Route 66?
Have you traveled it or lived along it?
Do you have any fun civil engineering facts related to it?
At our annual Oklahoma ASCE meeting this year, we learned about the "Ribbon Road" which is a narrow section of road that was incorporated into the original Route 66, portions of which are still there. The fact that a 9 foot wide highway section was approved for incorporation into an interstate highway under 100 years ago shows just how quickly civil engineering has evolved to accommodate changes in transportation and traffic.
