During construction of highways, construction companies frequently apply blacktop one lane at a time, and at the end of the day, leave a vertical drop-off of 2 to 3 inches between lanes. This dramatic drop off is extremely dangerous to motorcycle drives, especially at night when it is impossible to see the drop off and the driver attempts to change lanes. It is difficult to maintain control of an articulated two-wheel vehicle under these conditions and dangerous accidents can result. Misplaced signs or absent warning signs aggravate the problem and leave the motorcycle driver without any warning of the dangerous condition. We have become aware of accidents that have occurred in just such conditions. The use of a notched wedge joint at the edge of the lane during construction can prevent injuries. If the construction company tapers the edge with a roller, the dramatic drop off becomes a gradual slope, making the area safer for motorcycle drivers. Recently we noticed inconsistent use of the notched wedge joint in Houston, Texas. During part of the project, the proper notch wedge joint was used and during part of the project it was not. Even changing lanes in a car we could notice the extreme drop, and risked overcorrecting. We’ve become aware of these dangerous drop-offs during roadway blacktop operation on major highways in Houston, including on I-10, the Beaumont highway, and I-59, the Southwest Freeway.
