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.
On Tuesday night, state workers replaced cones and barrels at the heavily traveled interchange in Weston with new striping on the roadway, after finding the reconfiguration reduced driver hesitation at the merging point, officials announced.
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.
