Restore94 traffic shifts may slow trips to Detroit airport

Travelers planning to reach Detroit Metropolitan Wayne County Airport in the coming days are being encouraged to allow extra time, as construction-related traffic shifts on Interstate 94 near the airport continue to slow traffic and increase the risk of delays.

Long-term Restore94 work enters a disruptive phase

The Restore94 program is a multiyear effort to rebuild and modernize key stretches of Interstate 94 in southeast Michigan, including the busy corridor that links Detroit to Detroit Metropolitan Wayne County Airport. Publicly available information indicates that current work in the Romulus and Dearborn area has moved into a phase that relies heavily on lane reductions and lane shifts to keep traffic moving while bridges, pavement and ramp systems are rebuilt.

Construction plans describe a staged approach intended to maintain traffic in both directions while crews work in the closed portions of the roadway. That strategy has resulted in narrowed lanes, reduced shoulders and temporary configurations that can feel unfamiliar to regular commuters. Drivers heading to the airport from Detroit or Ann Arbor are encountering these changes over several miles, which can compress traffic and slow travel even outside traditional rush-hour periods.

The Restore94 work is part of a broader, long-range modernization of I-94 in and around Detroit that has been discussed for more than a decade. Recent project documentation and planning reports emphasize the need to address aging bridges and pavement, improve safety and update interchanges that serve major destinations, including the airport. For motorists, that translates into several construction seasons of recurring lane closures and traffic shifts before the improvements are complete.

Lane closures, ramp changes and tighter merge areas

Recent notices and media coverage indicate that drivers are seeing a combination of left-lane and right-lane closures on I-94 in the vicinity of the airport, often changing by weekend or by week as crews move to different segments. In some locations, all traffic has been shifted to one side of the freeway while the opposite side is reconstructed, creating a two-way traffic pattern separated by barriers.

These changes can be particularly challenging near entrance and exit ramps, where the distance for merging is temporarily reduced. Shorter weave areas leave less room for drivers to move across lanes to reach the appropriate exit for the airport, increasing the likelihood of sudden lane changes and braking. Travel-time reports and commuter accounts point to slowdowns forming quickly in these compressed merge zones, even when no crashes are reported.

In addition to mainline lane shifts, some access points that serve airport-bound traffic have been closed or partially restricted at various times, with detours routing drivers to neighboring interchanges. When a familiar ramp is closed, motorists who miss posted detour signs may find themselves passing the airport exit and needing to loop back, adding several minutes to their trip. The combination of changing patterns, frequent signage and heavy regional traffic has contributed to a perception of unpredictable conditions along the corridor.

Expected impacts for airline passengers and airport workers

For airline passengers, the most immediate effect of the Restore94 traffic shifts is the need to build a larger buffer into the drive to Detroit Metropolitan Airport. Ground travel that might normally take 20 to 30 minutes from central Detroit or Ann Arbor can stretch significantly when congestion builds near a lane drop or lane shift. Transportation planners and travel advisories commonly recommend arriving at the airport two hours before domestic flights and three hours before international departures, and the current construction adds another factor to consider.

Airport employees, ground transportation providers and frequent fliers who rely on I-94 may feel the impact even more acutely. Shuttle services, ride-hailing drivers and parking-lot operators must adjust schedules to account for recurring slowdowns, particularly during weekday peak periods and busy travel weekends. When congestion spills onto connecting routes, such as I-275 and key surface streets leading into the airport, delays can extend beyond the immediate construction zone.

There is also an operational dimension for airlines and airport managers. While flight operations are primarily affected by weather and air traffic conditions, high volumes of late-arriving passengers due to roadway congestion can complicate check-in and security screening flows. Publicly available planning documents for the corridor improvements acknowledge the importance of maintaining reliable access to the region’s primary air hub while construction is underway, but also note that periods of disruption are unavoidable when working in such a constrained and heavily used corridor.

Alternate routes and timing strategies for drivers

Transportation agencies and local travel advisories generally encourage motorists bound for the airport to consider alternate freeway connections when conditions on I-94 deteriorate. Depending on the origin, routes that incorporate I-275, I-96, US-23 or M-14 may provide a more reliable path, even if the total distance is slightly longer. Some drivers departing from western suburbs, for example, may find it faster to use I-275 to approach the airport from the south rather than remaining on I-94 through an active work zone.

Time of day is another important factor. Reports from commuters suggest that the most severe delays tend to occur during weekday morning and evening peaks, as regional traffic mixes with airport-bound travelers and commercial vehicles. Midday and late-evening hours may offer smoother conditions, although weekend lane closures for specific construction tasks can still trigger heavy backups. Checking current travel times and incident reports before leaving remains one of the most effective ways to avoid unexpected delays.

For those who must use I-94 directly to reach the airport, experts often recommend maintaining flexible departure plans during the most intensive construction phases. That can include scheduling flights outside of the busiest roadway periods when possible, arranging shared rides to reduce the number of vehicles on the corridor, or using off-airport parking options that provide shuttle services familiar with current detours. Taking a few minutes to review the latest closure information before departure can help drivers choose the most efficient entrance and exit ramps in a shifting construction landscape.

What travelers should watch for in the weeks ahead

Project timelines and phasing plans indicate that I-94 work between Romulus and Dearborn will continue through multiple upcoming construction seasons, with periodic adjustments to lane configurations as milestones are reached. In the near term, travelers can expect continued use of traffic shifts, nighttime and weekend lane closures, and intermittent ramp closures that directly affect access to Detroit Metropolitan Airport.

Publicly available project communications often highlight key transitions, such as moving traffic to newly rebuilt lanes or beginning reconstruction of major bridges near the airport. Each of these transitions can bring a new learning curve for drivers as they adapt to updated patterns. Frequent travelers may wish to monitor project updates, regional traffic maps and local news reports that summarize the most significant changes from week to week.

For now, transportation planners and travel experts are generally aligned on one point: anyone heading to Detroit Metropolitan Airport by car should budget extra time and remain prepared for slow-moving traffic near I-94 work zones. With construction activity expected to continue for several years, the Restore94 project is set to remain a defining feature of the drive to one of the Midwest’s busiest airports.
