Lynn Ridley lives on the corner of 5th and Kemp in Missoula. Lately, it's been noisy outside her window -- honking horns and screeching tires.

"People going down Kemp aren't used to the stop sign being there, and people going across Fifth Street are basically just flying through, now that they don't have to stop. There's been several near-accidents."

According to city officials, slow progress on the Third Street construction project forced them to detour all traffic onto Fifth. Since then, they've doubled their speed.

The intersections of Fifth and Kemp and Fifth and Johnson normally have stop signs for traffic on Fifth.

Additional cars on Fifth meant City Construction Manager Doug Harby had to figure out how to keep traffic flowing. The stop signs for traffic on Fifth were covered up on Tuesday, while temporary stop signs were put in place for traffic on Johnson and Kemp.

Residents, including Ridley, disagree and would prefer a four-way stop intersection. Harby says they tried that for a day. The result was traffic backed up for blocks and residents trapped in their driveways during rush hours.

The signs on Fifth were covered the next day.

Yet, drivers are still confused. It's the complete opposite of how the intersection is normally set up.

NBC Montana spotted drivers unsure of whether to stop or go as they approached the intersection Wednesday morning.  Some cars turned from Johnson onto Fifth perilously close to oncoming traffic.

There's another issue as well -- from Johnson and Kemp, drivers can only see the back of the stop signs, which look normal since only the front of the Fifth Street signs are covered. Some drivers could think that they are at a four-way stop intersection.

When NBC Montana brought this to Harby's attention, he stated that he would cover the back of the stop signs on Fifth, so that drivers in all directions would be sure they know who has the right of way.

Harby says he expects traffic to be smoother after a week as drivers get used to how the reorganized intersections work. The detour will continue until September.
