State transportation officials are extending a pilot program that might permanently remove the double-merge traffic pattern at the interchange of two of the state’s busiest highways, the Massachusetts Turnpikecq and Interstate 95, also known as Route 128.

The initial trial period of the single-merge pattern cut an average of 20 minutes from morning drivers’ commuting time, according to a transportation department statement. Full story for BostonGlobe.com subscribers.
