D. Harris, an engineer for the Virginia Highway Department. "Arlington County and Fairfax County agreed a year ago to call it the Custis Memorial Parkway. We've even ordered the signs for the entrances.<br />"The only thing that hasn't been done is for final approval to be granted. But that's just dotting I's and crossing T's. It's settled. This is no time to be drumming up business."}}</ref> a [[toll road]] with variable tolls during peak hours.<ref>{{Cite web|title=66 Express Lanes - Inside the Beltway :: About the Lanes|url=http://66expresslanes.org/about_the_lanes/default.asp|access-date=2021-01-09|website=66expresslanes.org}}</ref> The road narrows to four lanes as it heads through [[Arlington County, Virginia|Arlington County]]. The parkway meets [[Virginia State Route 7|SR&nbsp;7]] (Leesburg Pike) at a full interchange. [[Virginia State Route 267|SR&nbsp;267]] (Dulles Toll Road) meets the parkway with an eastbound entrance and westbound exit. Continuing through neighborhoods, the route yet again meets US&nbsp;29 at an incomplete interchange and continues east into Arlington County, meeting [[Virginia State Route 120|SR&nbsp;120]] (Glebe Road) and continuing to Arlington County. It meets [[Spout Run Parkway]] and enters [[Rosslyn, Virginia|Rosslyn]]. The freeway turns southeast and runs in between US&nbsp;29 as it approaches the [[Theodore Roosevelt Bridge]], reaching another eastbound entrance and westbound exit as US&nbsp;29 continues north on the [[Key Bridge (Washington, D.C.)|Key Bridge]]. It then has a complex interchange with [[George Washington Memorial Parkway|George Washington Parkway]] and [[Virginia State Route 110|SR&nbsp;110]] (Richmond Highway), providing access to [[Alexandria, Virginia|Alexandria]] and [[the Pentagon]], respectively. US&nbsp;50 ([[Arlington Boulevard]]) merges onto the highway with a westbound exit and eastbound entrance and the two traverse the bridge.

The "Custis Memorial Parkway" name commemorates the Custis family, several of whose members (including [[Martha Dandridge Custis Washington]], [[George Washington Parke Custis]], [[Eleanor "Nelly" Parke Custis Lewis]] and [[Mary Anna Randolph Custis Lee]]) played prominent roles in [[Northern Virginia]]'s history. Because of its terminus in the [[Shenandoah Valley]], some early planning documents refer to I-66 as the "Shenandoah Freeway", although the name did not enter common use.<ref>{{cite web|title=Department of Planning & Zoning – Planning Zoning|url=http://www.fairfaxcounty.gov/dpz/comprehensiveplan/planhistoric/1984_documents/1984_transportation.pdf|url-status=live|archive-url=https://web.archive.org/web/20170208064206/http://www.fairfaxcounty.gov/dpz/comprehensiveplan/planhistoric/1984_documents/1984_transportation.pdf|archive-date=February 8, 2017|access-date=May 3, 2018|website=www.fairfaxcounty.gov|df=mdy-all}}</ref>

Between the Capital Beltway and the Theodore Roosevelt Bridge, the eastbound (inbound) roadway is a [[high-occupancy toll]] (HOT) road from 5:30 to 9:30&nbsp;am, and the westbound (outbound) roadway is an HOT road from 3:00 to 7:00&nbsp;pm. (Westbound tolling begins after exit 73 to US 29, in order to allow traffic crossing the bridge an opportunity to transfer to free roads.) [[E-ZPass]] is required for all vehicles except motorcycles, including Dulles Airport users. I-66 is free during those times for HOV-3+ drivers with an E-ZPass Flex and for motorcycles. Other drivers must pay a variable toll depending on current traffic levels. Outside of these hours, I-66 is free for all drivers to use.<ref name="express-lanes">{{Cite web|title=66 Express Lanes - Inside the Beltway :: Using the Lanes|url=http://66expresslanes.org/using_the_lanes/default.asp|access-date=2019-09-02|website=66expresslanes.org}}</ref>
