I-94 Westbound Lane Reconfiguration
Structural, Survey, Transportation | Wisconsin | Back
Challenge
Following the construction of the Marquette Interchange, WisDOT needed to add a fourth lane to a 2.6-mile stretch of westbound I-94 in Milwaukee County to alleviate congestion approaching the yet reconfigured stadium interchange. Kapur was tasked with finding a way to fit this additional through lane in a highly constrained corridor measuring only 45 to 48 feet wide.
Solution
Kapur led the design and plan preparation for the I-94 westbound restriping project, which involved pavement marking restriping of I-94 and I-794 westbound. Kapur’s design to add a fourth lane included 11-foot driving lanes, 2-foot shoulders, solid white pavement marking lines, and barrier wall reflectors. A crash investigation site was included to give vehicles in distress a safe place to maneuver from live traffic. To accommodate the design, median barriers were modified, and shoulders were reconstructed to carry truck traffic.
