Death of bin Laden provides opportunity for our nation
With the recent demise of one Osama bin Laden, would this not be an ideal time for our president to declare: “Mission accomplished! I’m bringing the troops home; we have far bigger concerns to address here!”?
Mr. President: “Carpe Diem!”

Springtime in Colorado brings more than May flowers
Spring is in full swing, and as Coloradans welcome the warmer temperatures, it may also be a time of frustration for drivers. Fluctuating temperatures that are warmer during the day and colder at night create the freeze-thaw effect that increases the potential for rockfall and accelerates the ability for a pothole to form. During rain and spring snow showers and in the days following, the potential for these occurrences is the greatest.
“Whether you are traveling in the city or in the high country, it’s especially critical this time of year that you keep your eye on the roadway ahead so that you can avoid a rock that may have fallen or a pothole that has surfaced,” said CDOT executive director Don Hunt. “We try very hard to be proactive and prevent rockfall and potholes from happening through the use of quality materials and preventative maintenance, but we do live in Colorado, and our weather conditions create an environment where hazards such as these are going to occur at some level despite our best efforts.”
Potholes are created when pavement or the base material beneath it cannot support the weight of the traffic. The factors that contribute to this problem are traffic and water. Pavement develops cracks over time due to traffic and/or water freezing and expanding. When water seeps into the pavement, it can wash away or erode the base material underneath the pavement, leaving nothing to support it. When traffic passes over it, that’s when it collapses and the pothole is formed.
Because of temperatures and wet conditions, potholes are currently being addressed with temporary fixes that involve tar and gravel — known as a “cold patch.” When the weather gets warmer, CDOT crews will use liquid asphalt — the “hot patch” — for a more permanent repair.
In the last year, CDOT maintenance crews have repaired more than 9,000 potholes in the Denver area alone and repaired and conducted maintenance on more than 4.2 million square yards of roadway surface across the state. In addition, CDOT spends more than $40 million annually on preventative maintenance work including resurfacing and crack sealing.
