Your story "A Green(er) Way about the JC Greenway Trail" was very informative. It is wonderful to have a great resource like this available. As your article pointed out however, without appropriate ways to cross Missouri Boulevard and U.S. 50/63 bicyclists are in real danger from traffic.
Driving on Missouri Boulevard poses dangers from traffic and traffic patterns not only for cars, but especially for pedestrians and bicyclists. If you live on the opposite side of Missouri Boulevard from the trail and want to get there safely about the only way to do so is to cross at Bolivar (by St. Mary's Health Center) as your article indicated. While perhaps the safest way to cross, Bolivar certainly is not convenient for those living farther west.
If cross signals were posted at Dix Road and perhaps one or two additional intersections and bike lanes added to major streets, bikers could use the trail as a realistic means of transportation from all parts of town.
Unfortunately, the decades old traffic situation of Missouri Boulevard never seems to be dealt with by the city or state. I hope your article will be a catalyst to encourage residents to contact their City Council member and state officials at MoDOT to raise concern about the lack of safe pedestrian and bicycle crossings on Missouri Boulevard and the general lack of bicycle lanes throughout the city.
With appropriate and safe ways to get to it, the JC Greenway Trail can be a useful, safe, energy saving and convenient resource for all citizens of and visitors to Jefferson City.
