Example entries in .list files Make .list · Examples · Updates · Users' Stats · Highway Browser   Below are several example entries and tips for a creating the .list file. Always look up the highway labels in the Highway Browser. The Browser maps each entry/exit point along each route and displays the label for each. While there are some rules of thumb for predicting the right labels, using the Browser is the only way to always find the correct label. Use the labels for the ends of each segment of highway in your .list file. Highway segment within a single state. For the segment of I-80 between Exits 161 and 224 in Pennsylvania, look up the labels for those interchanges in the Highway Browser. The Browser lists the labels as 161 and 224. Enter the following line into your .list file: PA I-80 161 224 Highway segment crossing into multiple states. To enter the segment of I-81 between Exit 300 in Virginia and Exit 10 in New York, break up the segment into smaller pieces by state. The Virginia segment begins at Exit 300 and ends at the West Virginia border, so use endlabels 300 and VA/WV for the Virginia segment. I-81 runs from border to border in West Virginia, Maryland, and Pennsylvania, so use endlabels WV/MD, MD/PA, and PA/NY for these states. The New York segment begins at the Pennsylvania border and ends at Exit 10, so use endlabels PA/NY and 10. Enter the following lines in your .list file for this whole segment: VA I-81 300 VA/WV WV I-81 VA/WV WV/MD MD I-81 WV/MD MD/PA PA I-81 MD/PA PA/NY NY I-81 PA/NY 10 Beltways within a single state. Single-state beltways are treated as a highway beginning and ending at the same reset point after looping around a city. For example, the Baltimore Beltway (Maryland I-695) resets at the southern point labeled as both 0 and 48. If the segment you wish to enter crosses that point, split your segment into two at that point. Consider first the segment of the Baltimore Beltway (I-695) between exits 17 and 31 along the northern side of Baltimore. Since the labels run continuously from 17 to 31 without resetting (compare to next example), treat this segment simply as beginning at Exit 17 and ending at Exit 31: MD I-695 17 31 Now consider the southern segment of the Baltimore Beltway between the same Exits 17 and 31. The label numbers reset in this range: 17, 16, ..., 1, 0, 48, 44, ..., 31. Endabels 0 and 48 refer to the same point, and the beltway is treated as though it begins at 0, loops around the city, and ends at 48. With this in mind, treat your whole segment as two, one with ends at 0 and 17, and the other with ends at 31 and 48: MD I-695 0 17 MD I-695 31 48 To enter the entire Baltimore Beltway, use the two endlabels for the reset point: MD I-695 0 48 Beltways crossing into multiple states. Treat segments along these beltways just as you would any other segment that crosses into multiple states. Overlapping highways (multiplexes). Highways can overlap another highway so that the same freeway has two or even three concurrent numbers. Include separate lines in your .list file for each highway in overlaps. In Interstate overlaps, one highway will usually use the exit numbers of the other highway. In this case, the number of the other highway is part of the endlabel. For example, if you travelled all of I-84 in Pennsylvania, you also travelled on an overlapping piece of I-380. Include a line for each highway: PA I-84 0 PA/NY PA I-380 I-81 24 Interstate Peculiarities. A handful of highways demand special treatment: I-24 in Tennessee and Georgia. I-24 leaves Tennessee, briefly enters Georgia, and crosses back into Tennesee. Use TN I-24 for both the longer, western portion of I-24 in Tennessee. Use GA I-24 for the portion of I-24 in Georgia. Use TN I-24_E for the shorter, eastern portion of I-24 in Tennessee. I-26 in North Carolina. NC I-26 refers to the section of I-26 between I-240 in Asheboro and the NC/SC state line. NC I-26_W refers to the newer section of I-26 between the TN/NC state line and the US 19 interchange (Exit 9). The section of freeway between these routes is marked as a future Interstate highway and is not included as a clinchable Interstate. I-35E/W in Minnesota and Texas. I-35 splits into two routes, I-35E and I-35W, and recombines as I-35 in both Minnesota and Texas. In both states, I-35E is treated as part of I-35, and I-35W is treated as a separate route I-35W. I-73 and I-74 in North Carolina. The routes NC I-73 and NC I-74_E refer to the portion of signed I-73/I-74 south of Greensboro. Include an entry for each route if you have clinched a portion of this freeway. The route NC I-74 refers to the other piece of I-74 between the Virginia state line (concurrent with I-77) and the interchange with US 52 that is 17 miles to the southeast. The route NC I-74_S refers to the section of I-74 between Laurinburg and Pembroke. I-86 in New York. There are two discontiguous pieces of this highway. Use NY I-86 for the longer, western portion of I-86. Use NY I-86_E for the shortern, eastern portion of I-86. I-95 in New Jersey. The route NJ I-95 refers to the unsigned portion of I-95 beginning at the Pennsylvania border along the Pennsylvania Extension of the New Jersey Turnpike and following the New Jersey Turnpike northward to the signed portion that leads into New York state. The route NJ I-95_M refers to the signed portion of I-95 between Pennsylvania and US 1 on the north side of Trenton. I-95 splits into two parallel highways near Secaucus, NJ. The eastern highway is treated as part of NJ I-95, while the western highway is treated as a separate route NJ I-95_W. I-95 and I-495 in the District of Columbia. I-95/I-495 crosses the southernmost tip of the District of Columbia. Remember to include entries for both DC I-95 and DC I-495 if you have clinched this portion of highway. I-684 in New York and Connecticut. I-684 crosses from New York into Connecticut and returns to New York. Use NY I-684_S for the southern portion of I-684 in New York. Use CT I-684 for the portion of I-684 in Connecticut. Use NY I-684 for the northern portion of I-684 in New York.
