The new lanes would total 21 miles on both the north and south sides of the freeway.
UDOT Region One spokesman Vic Saunders said the  objective of the study is to obtain environmental clearance to connect  the Express Lanes on I-15 in central Davis County to those in Salt Lake  County, and to fill in missing sections in Weber and Davis counties.
 “The plan is to make it one continuous stretch, without any  interruptions on the busiest part of I-15 in the state,” Saunders said. UDOT hopes to have concept designs for the road  finalized by the end of the summer and public hearings will be held in  late fall. Final environmental clearance is expected by early spring of 2013 and construction would likely begin soon after. Standard Examiner
