6. Zoom in closer to the original point A. Scroll the mouse over the purple
shortest path line and you’ll see a white circle appear along the path.
This lets you change the calculated route to account for any variety of
factors (such as travel preference, known congestion or construction
areas, rerouting to avoid areas or known delays, and so on).
7. Start by placing the mouse over the turn onto I-264 and drag the
circle up to state route 58 (also known as Laskin Road or Virginia
Beach Boulevard—the other major east-west road just above and
parallel to I-264). The route will change by first having you drive
north on Atlantic Avenue, turning west on 58, then merging back
onto I-264 again a little later in the route. Even though it’s a small
change, you’ll see that the driving distance and estimated time have
changed. Answer Question 8.3. When you’re done, return the circle
back to its original starting point and the route will go back to how it
originally was.
Question 8.3 What is the new distance (and estimated driving time) of the
route using this new path? What would account for this?
8. Scroll across the map until you see where the route crossed I-64 (about
two-thirds of the way between the two points). I-64 is the major highway
into the Hampton Roads area. Let’s throw another change into the
scenario—say, for instance, that there is heavy construction on I-264
west of the I-64 intersection. At the intersection, move the circle off the
