This section of I-270 was a source of frequent backups during the late-afternoon hours until the interchange was rebuilt. A fatal accident in September 1999 spurred the rebuilding of the interchange, although the accident did not occur at that location happening a mile (1.6 km) east of the interchange. I-270 then passes various streets where every westbound exit connects to Dunn Road (and one must use Dunn Road to access I-270 with the only exceptions being the

One of the safety improvements is a "double white line" that motorists are not permitted to cross (violation of that could lead to a fine of $ 500) that is located at the exits for I-70 in the northbound lanes. Other safety implementations include a special

MoDOT has also identified the need of improving the I-270 corridor in northern St. Louis County, which could cost in the range of $ 200 million. The agency planned to widen the freeway from US 67 to Route 367 and rebuild every interchange (except I-170) and overpasses in this section.

On
September 13, 1999, a fatal accident involving a tractor-trailer occurred in the westbound lanes of I-270 in front of the now-defunct St. Thomas Aquinas-Mercy High School (now North County Christian School) in northern St. Louis County. This accident sped up efforts that led to the I-170/I-270

In 2008, MoDOT implemented new variable speed limits on I-270/I-255 with the normal limit being 60 mph (97 km/h). However, due to complaints from the public, these signs were planned to be updated in 2011 to advisory signs. A five-mile (8.0 km) section of I-270 between I-44 and
