Downtown Ramp Up Phase 4R/6R Causes Major Slowdowns at I-70/71 West Interchange

Morning Overview: Construction Peaks as Spring Approaches

Commuters in Columbus face a complex start to the week this Monday, March 9, 2026. With several multi-year infrastructure projects entering critical phases, the downtown "innerbelt" remains the primary point of congestion. Drivers should prepare for narrowed lanes and shifting patterns, particularly where I-70 and I-71 converge.

Major Arteries: I-70 and I-71 Downtown Ramp Up

The Downtown Ramp Up project remains the most significant factor for Monday morning travel. As Phase 4R/6R moves toward its scheduled completion in Fall 2026, commuters will encounter:

• West Interchange Restrictions: Ongoing lane reductions on I-70/I-71 near the Scioto River as crews finalize the new flyover ramp connections from Mound Street and improve traffic flow toward I-71 south.
• Front Street Gateway: While the new Front Street bridge is fully operational, surface-level work continues on the new Fulton Street ramp, leading to periodic off-peak lane closures that can cause back-ups during the early commute.
• Main Street to Broad Street: Initial preparatory work for the next phase of I-71 reconstruction has begun. Expect to see crews near the Town and Oak Street bridges as they conduct surveys and site preparation for future bridge replacements.

Secondary Routes and Local Projects

Beyond the highway system, several local arteries are seeing increased activity:

• Alum Creek Drive: Significant construction is ramping up between SR 317 and Groveport Road. Expect delays near the Big Walnut Creek bridges as contractors work on adding a third lane in each direction to improve access to the Rickenbacker area.
• West Broad Street: The LinkUS West Broad Transit-Oriented Development (TOD) Study is now in its active public phase following the kickoff meeting at the Hilltop library last week. While no major road closures are active today, increased utility work and survey teams are expected along the corridor.
• Dublin Gateway: Travelers heading toward Dublin via US-33 and SR-161 should note that while major interchange improvements are largely finished, minor landscaping and final signage installation may cause temporary shoulder closures.

COTA and Public Transit Alerts

The Central Ohio Transit Authority (COTA) is operating on a standard weekday schedule. Key updates for transit users include:

• New Mainstream App: Mainstream customers are encouraged to use the new customer-facing app for ride booking and tracking, which was rolled out earlier this year to replace phone-based scheduling.
• Tap to Pay: All fixed-route buses now support tap-to-pay via mobile wallets and enabled cards, which has significantly improved boarding efficiency during peak hours.
• Bus Stop Improvements: Following announcements last week, COTA has begun scheduled enhancements to several bus stops along high-traffic corridors to improve accessibility and passenger comfort.

Commuter Strategy

To navigate the I-70/71 split disruptions, the North Innerbelt (I-670) remains the most reliable alternate for east-west cross-town travel. For those heading to the Franklin County Courthouse or the southern downtown district, utilizing the newer Mound Street ramps from the west is recommended to avoid the heaviest congestion at the main interchange.
