I have always hated Interstate 270. Always. It is a little confusing with the local and HOV lanes. It is much, much wider than it ought to be, creating huge bottlenecks in northern Montgomery County and at the Beltway. It is preposterously ugly, unbearably congested, and I feel particularly unsafe driving it. It is, in my humble opinion, very poorly planned. The last thing we need is more of it. But that is what they want to give us.
Lots of people travel this corridor in both directions every day. Frederick County has a population of a quarter million and growing. The Bethesda-Gaithersburg-Frederick corridor has a population encroaching on five times that number, or roughly 20% of the Metropolitan area population. Downtown DC and Frederick are about 40 miles apart from each other. So this is a long corridor with a lot of people on it. A transportation solution must be found.
Obviously MARC's Brunswick Line is not getting it done. Its circuitous route through Brunswick adds several additional miles to the trip. Stops at small stations like Garrett Park, Washington Grove, Boyds, Barnesville, and Dickerson. Only 7000 people are riding this line daily (warning: pdf), and it is pushing its capacity. Even MARC's 2035 plan (pdf) only raise the capacity 26,000 per day (pdf). Meanwhile, between 75,000 and 108,000 vehicles clog I-270 every day. Imagine if we were talking about a solution that was faster than an expanded freeway or an improved MARC.
Widening I-270 is a colossal failure of an idea. Creating a bigger bottleneck at the Beltway for commuters from Frederick is just going to increase the number of cars that will sit on the parking lot that is 270 southbound in the morning. Here is my vision for a rail solution:

If local transit (light rail, buses, etc.) ferried these commuters to a few stations, the trains could make fewer stops and travel at higher speeds. A system like this, I envision an average speed of 90 mph. Eight stops along the way, that's it. Stops at major transit centers and major suburbs along I-270.
There is nothing on the books for a direct high speed service between DC and Frederick. There are plenty of other transit priorities at this time. And I understand that some people have no choice but to drive to their jobs. I am one of them. But I live six miles from my job. If I am going to subsidize someone else's extra-long commute, I want to do it with a system that will work, not one that will only increase the number of cars that are wasting fuel while sitting idly on a congested freeway.
