Temporary Speed Limit Reduction on County Road 121

At the June 13, 2022 meeting, the Board approved Resolution No. 2022-125 temporarily reducing the speed limit on County Road 121 from the Duval County line to County Road 2 to 45 mph. This is being done at the recommendation of Engineering Services and the Florida Department of Transportation in an effort to improve motorist safety due to current road conditions. New speed limit signs were put in place yesterday.

As previously announced, the State awarded the County $9 million in Legislative funding during the 2021 Legislative Session for repair and resurfacing of the southern most portion of County Road 121. Project design is anticipated to begin in late summer/early fall 2022. Construction is anticipated to begin early 2023 and will take six to nine months to complete.

Given the approximate two-year process to complete repairing of the southern half of the CR121 corridor, the Nassau County Road Department has been working diligently to make temporary asphalt repairs to the road by removing loose asphalt and debris; recompacting the base; filling the holes with tackifier, a compound that increases stickiness; filling the holes with a new asphalt mix; and then tamping it into place, and packing it tightly before leveling it to the surrounding road. The Road Department has also to worked to remove the accumulation of soil along portions of the roadway’s shoulders to allow rain water to drain away more quickly from the paved surface.

Following completion of the repair and resurfacing project, the roadway will be re-evaluated to reimplement the 55 mph speed limit.
