| 1906 | A. W. Nichols of Greenville, MI, writes a letter to Good Roads Magazine to report that an object lesson road built by OPRI on July 29-31, 1902, with Director Martin Dodge present, was still in excellent condition even though "not a dime has been expended upon it since its construction." |
| 1951 | On the Henry G. Shirley Memorial Highway, BPR works with the Virginia State Department of Highways and the Williams Construction Company to complete construction of a pit and slab for the load cells and electrical equipment to test weigh-in-motion equipment. The experiment, near the intersection with U.S. 1, leads to the conclusion that a good possibility exists for improving accuracy to the point that weighing trucks in motion will provide data that is as accurate as weighing trucks statically. |
| 1970 | Under an FHWA contract and with cooperation of the Massachusetts Department of Public Works, a computerized traffic control system is activated to help drivers merge from the Main Street ramp onto Route 128 in Woburn. The Raytheon Company designed the "Merging Control Traffic System." |
