The latest and greatest monitoring results from the Oracle Road wildlife crossings
In March 2019, the Arizona Game and Fish Department (AGFD) released their latest monitoring results from the Oracle Road wildlife crossings. AGFD typically releases monitoring results twice a year so we should have an updated monitoring report sometime this fall.
Two summary graphs from the report are highlighted below:
This graph shows the total mule deer crossings at both the Oracle Road underpass and bridge. Mule deer started using the bridge almost immediately after construction finished and have been used it steadily ever since (blue line). More recently, mule deer have become more acclimated to using the underpass, with increasing numbers successfully crossing all the way through the underpass since Winter 2018. It is well established that some wildlife species will use wildlife crossings right away with little acclimation while others may take years before they become acclimated and then will start using the crossing regularly.
This graph shows the total crossings by all wildlife species at both the Oracle Road underpass and bridge. Wildlife started using both crossings very soon after construction completed and have been using them steadily ever since. This new connectivity across Oracle Road increases the health of our local wildlife populations by allowing them to reach new home ranges and find mates (which then supports healthy genetic diversity) and also increases the safety of Oracle Road itself with a reduction in wildlife-vehicle collisions. Miles of wildlife fencing was also installed as part of this project – the fencing directs wildlife to the crossings themselves and was designed using the best available science to accommodate a wide range of wildlife species.

On July 16, 2021, the Arizona Department of Transportation and Federal Highways Administration released the Tier 1 Final Environmental Impact Statement (FEIS). The FEIS now identifies TWO possible Preferred Alternatives, a West Option through Avra Valley AND an East Option that co-locates I-11 with I-19 and I-10 through the Tucson region. Action #1: Please ACT […]
