The route links I-15, which bypasses downtown Great Falls to the west, to the center of Great Falls. As its Business Loop designation implies, I-15 Business terminates at I-15 (concurrent with U.S. Route 89 and Montana Highway 200 through western Great Falls) at each end. The southernmost {{convert|0.83|mi|km}} of the route from the interchange with I-15 to Fox Farm Road is designated, but not signed, as Interstate 315.[2] It is the second shortest interstate in the country; only the unsigned Interstate 878 is shorter. Route descriptionI-15 Business begins at I-15 exit 278 a short distance west of Great Falls. Here, US 89 and MT 200 separate from I-15 and merge with I-15 Business. Additionally, Montana Highway 3 begins at the interchange and follows the three routes to the east. Just east of the interchange with I-15, BL 15 interchanges with 14th Street. The Interstate Highway-standard conditions come to an end a short distance to the east at an intersection with Fox Farm Road.[3] Here, the {{convert|0.83|mi|km|2|sing=on}}[4] I-315 (designated along BL 15 from I-15 to Fox Farm Road) comes to an end[5] while BL 15, US 89, MT 3, and MT 200 continue across the Missouri River into downtown Great Falls.[3] Within downtown, the four routes remain concurrent along 10th Avenue South to the parallel one-way couplet of 5th and 6th Streets. BL 15 northbound separates from US 89/MT 3/MT 200 at 6th Street, following the street northward through the city to the one-way 2nd Avenue North near the city center. BL 15 turns to the west, following 2nd to Park Street, then Park south to Central Avenue, where BL 15 northbound rejoins the routing of BL 15 southbound. Between Central Avenue and 10th Avenue South, BL 15 southbound is routed along 1st Avenue North east to 5th Street South, then 5th south to 10th Avenue.[3] BL 15 follows Central Avenue to the west, crossing the Missouri River once more as it exits downtown. After several intersections with local streets, BL 15 terminates at I-15 exit 280. Central Avenue, however, continues westward from the exit.[3] Major intersections{{Jcttop|exit|state=MT|county=Cascade|location=Great Falls|length_ref=}}{{MTint|exit|type=concur |mile=0.000 |exit=— |road={{Jct|state=MT|I|15|US|89|dir2=North|MT|200|dir3=West|city1=Helena}} {{Jct|state=MT|I|315|nolink1=y|noshield1=y|dir1=begins|MT|3|dir2=begins}} |notes=West end of I-315, US 89, MT 3, and MT 200 overlaps }}{{MTint|exit |mile=0.335 |exit=0 |road=14th Street Southwest }}{{MTint|exit |type=concur |mile=0.828 |road={{Jct|state=MT|I|315|nolink1=y|noshield1=y|dir1=ends|road=Fox Farm Road, 6th Street Southwest}} |notes=East end of I-315 overlap }}{{MTint|exit |mile=2.256 |road=5th Street South (southbound) |notes=One-way street }}{{MTint|exit |type=concur |mile=2.341 |road={{Jct|state=MT|US|89|dir1=South|MT|3|dir2=South|MT|200|dir3=East|name3=10th Avenue South}} |notes=East end of US 89, MT 3, and MT 200 overlaps, I-15 Bus. turns onto 6th Street South (one-way street) }}{{MTint|exit |espan=5 |mile=3.177 |road=1st Avenue North (eastbound) |notes=One-way street }}{{MTint |mile=3.252 |road=2nd Avenue North (westbound) |notes=One-way street }}{{MTint |mile=3.664 |road=Park Drive }}{{MTint |mile=3.730 |road=1st Avenue North }}{{MTint |mile=5.834 |road={{Jct|state=MT|I|15|US|89|MT|200|city1=Shelby}} }}{{Jctbtm|keys=concur}} See also{{see also|Business routes of Interstate 15#Montana}}References{{AttachedKML|display=title,inline}}1. ^{{cite web|url=http://www.kurumi.com/roads/3di/ix15.html|title=Kurumi entry (I-115 to I-515)|publisher=|accessdate=5 October 2014}} {{Great Falls, Montana}}{{3di|15}}2. ^{{cite web|url=http://www.interstate-guide.com/i-315_mt.html|title=Interstate 315 Montana @ Interstate-Guide.com|accessdate=2007-09-24}} (has pictures showing that I-315 is signed as BL 15) 3. ^1 2 3 {{Cite map | publisher = Rand McNally | title = The Road Atlas '07 | year = 2007| page = 61 | section = M16 and N16 }} 4. ^{{cite web |url= https://www.fhwa.dot.gov/planning/national_highway_system/interstate_highway_system/routefinder/table02.cfm |title=Route Log and Finder List - Interstate System: Table 2|publisher=FHWA |accessdate= 2007-09-24}} 5. ^{{cite map|url=http://www.mdt.mt.gov/other/urban_maps/fc_internet/GREATFALLSFUNC.PDF|title=Great Falls - Cascade County|publisher=Montana Department of Transportation|date=2001|accessdate=2007-09-24}} 5 : Business Interstate Highways|Interstate Highways in Montana|Interstate 15|Great Falls, Montana|Transportation in Cascade County, Montana |
