| 1925 | Construction begins on a 10.16-mile section of State Route 6 between Columbia and Mt. Pleasant, TN (completed October 2). At the contractor's request, BPR efficiency engineers make time studies of construction operations on this Federal-aid project. The experts make several suggestions to increase daily output. For example, use of a double hose connection on the cement mixer adds 20-30 minutes of running time each day and increases daily output by about 75 square yards. |
| 1962 | Administrator Rex Whitton testifies before the House Subcommittee on Roads in support of H.R. 11199, the Federal-Aid Highway Act of 1962, citing particularly its provisions for urban transportation. (See April 5, 1962.) |
