BARRINGTON, Ill. — Route 14 reopened Friday on a new temporary four-lane roadway at 3:30 p.m., restoring a key east-west connection through downtown Barrington even as construction on the long-planned underpass continues, according to Daily Herald. Lake Zurich Road also reopened as a temporary two-lane roadway at the same time, village officials said in a notice carried by the Barrington Hills Observer.

The milestone follows a full temporary closure in September that allowed crews to build out the detour network and prepare for the next phase of the U.S. Route 14 grade-separation project. The project website at Village of Barrington continues to post renderings and schedule updates, with substantial completion anticipated in 2027, according to the village and the Daily Herald.

What changed on Oct. 31

The October reopening delivered visible, practical changes aimed at moving traffic safely through the work zone while crews build the underpass below. During the full temporary closure that began in September, workers completed several pieces central to the detour and safety plan, according to the Daily Herald and the Barrington Hills Observer:

  • Four new lanes of pavement on a temporary alignment for Route 14
  • Temporary railroad tracks to maintain rail operations during construction
  • A full temporary railroad crossing, including two pedestrian gates
  • A temporary sidewalk to keep foot traffic moving through the area

Village officials say these interim elements will remain in place while the permanent underpass is built, with adjustments as work progresses, the project website at Village of Barrington notes.

How drivers and businesses are affected

Friday’s reopening is expected to ease daily backups that came with weeks of detours and lane reductions, even as the work zone stays active. Local leaders have repeatedly stressed that commerce can and should continue near the project area. “All businesses located in the Local Traffic Only areas along Northwest Highway and Lake Zurich Road remain open during the temporary closure of Route 14. According to local officials, access to these businesses and community organizations is not affected by the roadwork,” local officials told Lake County Gazette.

That message continued at the reopening: residents were encouraged to patronize local shops and restaurants during construction, according to the Daily Herald. With Route 14 and Lake Zurich Road now carrying traffic again—albeit on temporary alignments—drivers should expect changing patterns, posted work-zone speeds and periodic daytime lane shifts as crews advance the underpass.

What it took to get here

The return of through-traffic caps months of preparatory work that set the stage for heavy construction. Earlier this year, crews focused on utility relocations, demolition and earthmoving, and installing culverts at key locations including Elm Road and Hough Street, steps documented by the Barrington Hills Observer. The village has used its dedicated project site to coordinate schedules and post advisories on phasing and access, according to Village of Barrington.

The underpass formally broke ground in April 2025, with officials highlighting goals such as improved safety, stronger connectivity and reduced congestion—key outcomes once Route 14 no longer intersects the railroad at grade, according to Barrington Hills (Village).

Where the project goes next

With the temporary four-lane Route 14 and two-lane Lake Zurich Road in service, the focus shifts to constructing the permanent underpass below the rail line and tying the final roadway into place. Substantial completion is targeted for 2027, a timeline that reflects continued staging to keep traffic and trains moving while the excavation, structure work and final paving take shape, according to Village of Barrington and the Daily Herald.

For commuters, that means a measure of relief now—two through lanes each way on Route 14—along with the reality of an active work zone for the next several seasons. For downtown merchants and institutions, access remains in place, and the prompt from officials to “shop local” remains loud and clear, as reported by Lake County Gazette and echoed at the reopening by the Daily Herald.

Barrington has cleared a major hurdle; the next ones are measured in concrete pours, shifted barricades and patient commutes. The village’s project site at Village of Barrington promises regular updates as milestones approach. By 2027, the dust should settle into a redesigned Route 14 corridor built to move people and goods with fewer interruptions—an outcome that will ripple through daily school drop-offs, lunchtime errands and the region’s rush hour alike.
