Overhead Flashing Beacon Replacement ProgramIntersections with flashing overhead beacons and a two-way stop condition can be a safety hazard. These intersections can be dangerous because traffic on the side road that has a flashing red beacon may incorrectly assume that traffic on the main road also has a flashing red beacon and is supposed to stop. However, traffic on the main road has an overhead flashing yellow beacon and does not have to stop. Accidents can and do occur when traffic on the side road pulls out into the path of traffic on the main road.
The Iowa DOT's Office of Traffic and Safety has some funds through the Transportation Safety Improvement Program to identify and replace these beacons. The overhead beacons would be replaced with stop sign mounted flashing red lights for the side road and advance warning signs with yellow flashing lights for the main road.
Initially these will be replaced on an as-requested basis. In the future, a project may be put together to do a systematic replacement.
Intent of program
To provide funding to replace overhead flashing red and yellow beacons with stop sign mounted flashing red beacons for minor road traffic and yellow flashing beacons on the advanced warning signs for major road traffic.
Who is eligible to request funding?
All public agencies may request funding for use on any public road.
