Figure out a different way to grow, going to 16 or 20 lanes won't solve the problem.
You have a misconception. Yes, even though 270 has been widened several times, and it is still congested, you mistakenly think that other alternatives will solve the transportation problem. The reason that the highway is still congested is that the population of Montgomery County has also continued to grow. Whether you widen the highway or not, the population of the county will continue to grow. In 1980, the population of the county was 4.2M. In 2018, the population is just over 6.0M. That's 143% or 43% growth over 38 years. The reason that the highway is still congested is that the population has grown faster than the road and transit can accommodate. The county population is currently projected to continue to grow 0.33% to 0.8% annually. There is no way that mass transit alone can accommodate that volume of population growth. You are going to need a combination of mass transit upgrades and highway expansion to accommodate the growth.
There's no way around the problem that the Washington DC metro region is one of the fastest growing metropolitan regions of the US and we have to come up with ways to accommodate the influx of people. Mass transit alone is not going to do it.
