The proposal calls for modifying the trail at the south ramp
The south onramp onto northbound GWMP near the Airport Access Road (SR-233) bridge would be
widened to provide additional merging distance. This may require a minor shift of the Mount Vernon
Trail and the Mount Vernon Trail would be widened slightly. A safety barrier may be installed between the
widened GWMP onramp and the realigned trail. The Mount Vernon Trail crossing of the south GWMP
onramp would be enhanced with lane markings and signage, including rapid flashing beacons, to improve
safety for trail users. The potential for a future grade-separated crossing is under consideration. Light
poles in the vicinity of the onramp would be realigned and replaced in accordance with NPS GWMP
design standards.
