This study, completed in 2013, showed that the corridor frequently performed at near-failing levels of service (LOS grades D and E), with the High Rise Bridge itself outright failing, resulting in higher crash rates when compared to other areas in the region. This is because most of the interchange ramps were built to previous interstate standards and were based on then-rural development in the Western Chesapeake and Eastern Suffolk. In addition, since the start of tolling at the Elizabeth River Tunnels, the High Rise Bridge and the corridor has received a nearly 7% increase in traffic during peak hours, further exacerbating the problem.
