Between US 6 and I-25 and I-70 and Georgetown, perhaps a more humble addition of one extra lane on the uphill side of hills in the direction traffic.
I also believe that more 3 lane passing sections should be built along US 6 between I-70 and Golden.
I also agree that the two lanes should not be tolled.
You know, some sort of reversible lane implementation on I-70 from Floyd Hill to Vail seems to make a heck of a lot of sense for the mountains because the one way traffic is so easy to predict, unlike say in Denver or on US 36 where there is no clear cut "bad" direction to travel at a certain time.
In the "off" direction, 2 lanes seems to cut it just fine, and probably will for quite some time to come. If they expanded one more lane on each side, but during peak hours were somehow able to convert one of the lanes from the "off" direction traffic to be used for the high flow direction I would think it could go a very long way to alleviating congestion.
This would still require expansion of the entire corridor to 6 lanes though, that's a given. We can't ask for one way to go to 1 lane, because trucks would muck everything up, but if we expanded the highway and
allowed for reversible lanes, even if only for key sections, how could that not help tremendously? Basically you are getting an 4 lane expansion for the price of 2 maybe 3 max due to the special signage and crossovers that would be required.
