Kansas City drivers using Interstate 70 near 18th Street face another set of daytime lane and ramp closures this week. The Missouri Department of Transportation says crews will restrict traffic from Tuesday, August 18, through Friday, August 21, 2026, for bridge work on the Improve I-70 KC project.
If you commute through Jackson County, downtown stadium approaches, or the Benton curve area, these are not overnight-only inconveniences. MoDOT’s dated windows put closures into morning and midday travel, which is when airport runs, hotel shuttles, and game-day arrivals already stack up.
- When: Tuesday, Aug. 18, through Friday, Aug. 21, 2026, weather permitting.
- Where: I-70 near 18th Street in Kansas City for westbound bridge work over Indiana Avenue, 18th Street, and the KCT railroad.
- Tuesday pattern: Westbound right-lane and 18th Street ramp closures about 9 a.m. to 6 p.m.
- Wed and Fri pattern: Eastbound right-lane and Indiana Avenue ramp closures about 7 a.m. to 3 p.m.
- Traveler move: Leave earlier, avoid the closed ramps, and watch live MoDOT alerts before you commit.
What MoDOT scheduled this week
According to the MoDOT Improve I-70 KC notice published August 17, 2026, crews will work on the new I-70 westbound bridge over Indiana Avenue, 18th Street, and the KCT railroad.
On Tuesday, August 18, from about 9 a.m. until 6 p.m., the right lane closes on I-70 westbound from 23rd Street to Truman Road, and the ramp from 18th Street to I-70 westbound closes.
On Wednesday, August 19, and Friday, August 21, from about 7 a.m. until 3 p.m., the right lane closes on I-70 eastbound from Chestnut Avenue to 23rd Street, and the ramp from Indiana Avenue to I-70 eastbound closes. All work is weather permitting.
Local traffic reporting such as FOX4’s Improve I-70 coverage has already framed the larger Kansas City rebuild as a multi-year disruption corridor, which is why these short dated windows still matter for trip planning now.
Why this corridor keeps changing
Improve I-70 KC covers about five miles of Interstate 70 between The Paseo Boulevard and U.S. 40 and 31st Street. MoDOT says the stretch was built in the early 1960s and carries up to 120,000 vehicles a day.
The $237 million project is replacing aging infrastructure across 12 interchanges and 26 bridges, with construction described as beginning in spring 2025 and finishing by December 2028. That means travelers should expect recurring daytime and overnight restrictions long after this week’s bridge window ends.
MoDOT has also warned of a separate 11-month full closure between downtown and the stadiums in 2027. This week’s 18th Street work is not that closure, but it is part of the same rebuild that will keep changing downtown I-70 habits for years.
How to read the day-by-day pattern
Tuesday is the westbound problem set. If your trip needs the 18th Street westbound ramp or the right lane between 23rd Street and Truman Road during the middle of the day, shift earlier or later, or pick another entrance.
Wednesday and Friday flip the pressure to eastbound traffic. The Indiana Avenue eastbound ramp and the right lane from Chestnut Avenue to 23rd Street are the ones to avoid during the morning-to-early-afternoon window.
Thursday is not listed with those same daytime restrictions in the August 17 notice. Still verify live conditions before treating Thursday as fully open, because Improve I-70 KC can add short-term work without rewriting the weekly headline.
Who should change plans this week
Airport travelers using I-70 to or from Kansas City International should add buffer on Tuesday afternoon and on Wednesday or Friday mornings when the listed ramps are closed.
Hotel and downtown visitors should avoid treating 18th Street or Indiana Avenue as reliable I-70 on-ramps during the posted hours. Use an alternate entrance and confirm the live board before the final turn.
Stadium, convention, and cruise-ship-excursion traffic that funnels through the same east-side interchanges needs the same caution. A closed ramp can push everyone onto the next available exit and create secondary backups.
Overnight visitors can use Deep Arrival’s Kansas City RV parks and campgrounds guide when a delayed I-70 approach changes where you want to base for the night.
Leisure travelers heading to northeast Kansas City attractions should also check Deep Arrival’s Worlds of Fun guide before assuming the usual I-70 exits remain the fastest park approach during the posted hours.
If you are flying into the metro and then driving downtown, Southwest and other carriers still get you to the airport on schedule, but the highway piece is the variable. Deep Arrival’s Southwest Airlines guide covers the air side; MoDOT covers the road side.
Commercial drivers and fleet managers should treat Improve I-70 KC as an ongoing operations problem, not a one-week detour. Sign up for MoDOT project alerts if this corridor is part of a regular Kansas City delivery loop.
Pedestrian and local-access travelers near Indiana Avenue and 18th Street should watch for temporary signing when ramps close. Neighborhood cut-through traffic often rises when a freeway ramp disappears for the day.
| If you travel… | Do this |
|---|---|
| Westbound Tuesday 9 a.m. to 6 p.m. | Expect the right-lane closure and skip the 18th Street westbound ramp. |
| Eastbound Wed or Fri 7 a.m. to 3 p.m. | Expect the right-lane closure and skip the Indiana Avenue eastbound ramp. |
| To KCI or downtown hotels | Add buffer and confirm an alternate I-70 entrance before you leave. |
| For stadium or event traffic | Assume secondary backups on the next open exits and arrive earlier. |
| Later in 2026 or 2027 | Watch Improve I-70 KC alerts; this week is one window in a multi-year rebuild. |
- This week: Recheck MoDOT hours before Tuesday through Friday trips on I-70 near 18th Street.
- Ramps: Do not count on 18th Street westbound Tuesday or Indiana Avenue eastbound Wed and Fri.
- Alerts: Sign up for Improve I-70 KC updates if you drive the corridor often.
- Longer view: Treat 2027 downtown-to-stadium closure planning as separate from this week’s bridge work.
MoDOT reminds drivers that work zones can be moving operations or short-term lane closures, and that conditions change with weather. If a board or app disagrees with yesterday’s notice, follow the live field condition.
One practical habit helps more than memorizing every ramp name. Before you leave, open the MoDOT Kansas City district page or the Improve I-70 KC project page, confirm today’s hours, then pick the entrance that is still open. Do not rely on a cached maps pin from last month.
If you miss the window and hit a closed ramp anyway, do not stop on the shoulder to rethink the route. Continue to the next safe exit, reset navigation, and accept the five-minute penalty instead of creating a new hazard in the work zone.
Rideshare and hotel shuttle drivers should share the same day-of check with passengers. A guest who planned an 18th Street drop-off needs an alternate curb before the meter starts climbing in diverted traffic.

No. This is a dated bridge-work window. MoDOT has separately discussed a longer 2027 closure between downtown and the stadiums.
