I-264 Lane Control Signals Improvements
Working closely with the Virginia Department of Transportation (VDOT), Kimley-Horn provided replacements for end-of-life Dynamic Message Signs (DMS) along a 4-mile corridor on Interstate 264.
Kimley-Horn engineers replaced DMS with a total of 20 state-of-the-practice, color, LED dynamic Lane Control Signals, structural attachment modifications and new structures that comply with current Manual on Uniform Traffic Control Devices (MUTCD) sign/signal spacing in a hard-shoulder running lane application, and the associated static sign panels for motorist information legends.
VDOT’s existing signs along the corridor were implemented prior to any MUTCD DMS spacing guidelines for managed shoulder lanes, and did not comply once the standards were adopted. When coupled with a general state of disrepair, the signs were in need of replacement. Although MUTCD standards do not account for a corridor with interchanges, Kimley-Horn collaborated with VDOT and the Federal Highway Administration (FWHA) to define how to apply MUTCD standards to the corridor.
Kimley-Horn completed the DMS replacements and updates on time and under budget by utilizing existing structures for DMS or new signage. Our team coordinated with the VDOT’s Hampton Roads District structures staff to demonstrate our analysis of the proposed sign load, compared it to the existing load, and identified a solution for maintaining structural thresholds for the additional documented equipment.
