Two crashes that forced the closure of southbound I-25 just north of the Rockrimmon exit have been cleaned up.
All lanes of traffic are now open.
A total of seven vehicles were involved in the crashes, including two semi trucks.
Police say the first accident involved a fuel tanker truck that was driving southbound in the center lane of I-25. The driver of the tanker had to brake suddenly for a large cardboard box that was in the roadway. This resulted in a chain-reaction crash involving two SUV's, a sedan and a flatbed truck carrying a large piece of Caterpillar machinery.
A secondary accident that happened in the same area involved a pickup truck and a sedan.
The Colorado Springs Fire Department's HAZMAT unit was called to the crash because of a diesel fuel spill from the flatbed tractor trailer.
Three people suffered minor injuries. Two of them were taken to area hospitals.
Southbound I-25 was closed for over two hours following the crash. The lanes reopened at around 3:40 p.m.
