For over 25 years, ADOT has been using rubberized asphalt on the Arizona highway system. In addition to providing smoother and quieter rides for drivers, rubberized asphalt lasts longer and costs less. Another bonus is that ADOT has recycled more than 15 million tires over the years.Take a look at how it’s done.

J- turns are located on 4-lane divided highways and prevent direct crossing and left-turn movements. These side road movements are made indirectly by making a right turn, traveling about a quarter-mile on the divided main road, and then making a U-turn to proceed in the opposite direction on the main road toward the intended destination. A J-turn reduces a significant number of the severe, right-angle, “far” side crashes. Relative to other improvement concepts, it is a low-cost treatment that can be quickly implemented, does not require property acquisition or relocation of homes and businesses, and minimizes environmental impact.

With federal transportation spending outpacing tax receipts by some $1.25 billion/month, the cash balance of the Federal Highway Trust is drawing perilously close to the point where the U.S Department of Transportation will be obliged to institute cash management strategies—such as reimbursing states weekly rather than on a daily basis— to keep the Trust Fund account solvent. Based on current spending and revenue trends, this point —a cash balance of $4 billion—may be reached as early as late July according to some estimates.

Toll roads in America date back to colonial times. Entrepreneurs in the late 1700s and early 1800s requested and received charters from state governments, enabling them to raise money from investors to improve dirt tracks between towns into regularly maintained roads—in exchange for charging users a toll. Transportation historians have estimated that between 2,500 and 3,200 toll companies built and operated such roads in the 19th century, encompassing between 30,000 and 52,000 miles at various times. The first wave of toll roads occurred in the northeastern states in the late 1700s and early 1800s. And the same pattern was repeated in the western states, especially California, after the Civil War, as those states were settled.
This culvert jacking was part of Section B (Mainline Toll Plaza in Bensalem) for the Pennsylvania Turnpike / I-95 Interchange Project. The jacking occurred below I-276 as traffic flowed from the above highway, minimizing impacts to traffic. Urban Engineers (www.urbanengineers.com) is providing Construction Management for this project.
