Description
Deployment of 2+1 Road with Barrier in Colorado certainly has potential to improve safety where it replaces conventional 2-lane highways, primarily by preventing head on and sideswipe crashes. The Swedish design is most widely implemented and has a record of success, so Colorado drivers expect the "slow" lane to be the ending lane, and somewhat gentler tapers than Sweden employs.
