The I-95/395/495 Interchange is located in Springfield, Virginia. Extensive renovations included the addition of HOV lanes and associated ramps and bridges. The project is funded by the Federal Highway Administration through the Virginia Department of Transportation. Burgess & Niple, as subconsultant to HNTB, provided soil test borings for the preliminary study.
Aspects of testing included:
Special consideration had to be given to heavy traffic volumes in the interchange. Work schedules were adjusted during rush hours, holiday periods, and inclement weather. Permitting, stakeout coordination, and utility clearances required weeks of planning for each of the 36 proposed structures. The preliminary report included site description and proposed construction, detailed geologic setting, presentation of field and laboratory data, and estimated design parameters.
