from where it would continue to US 4 in Troy over "Alternate Route 7", the limited-access alignment of NY 7 through the northern suburbs of Albany. This would have been accomplished by having I-88 meet the New York State Thruway at exit 25, where it would connect to I-890. I-88 would continue to Troy over I-890 and an upgraded NY 7. In the early 1980s, the proposed connection with I-890 was scrapped in favor of a connection located to the west of exit 25 in Rotterdam. The extension to Troy was also eventually shelved, and thus the planned connections to the Adirondack Northway (I-87) and the toll-free part of I-90 between Thruway exit 24 and exit B1 on the Berkshire Connector were never built. As a result, the Thruway tolls are waived for all traffic that enters at exit 25A and heads west to exit 26 (I-890) or east to either exit 25 or 24 (I-890 or I-87/I-90, respectively). The first section of I-88 to open was the piece between Chenango Bridge (exit 2) and Sanitaria Springs (exit 4), which opened in the early 1970s. A second piece near Oneonta between exits 13 and 15 was opened to traffic . Construction progressed southwestward from Oneonta, with the freeway reaching Nineveh (exit 6) by 1977. The gap between Sanitaria Springs and Nineveh was filled by 1981. The focus then moved to the section of the expressway between Oneonta and Schenectady, which was completed from Oneonta to Duanesburg (exit 24) by 1981. The Duanesburg–Schenectady leg of I-88 was opened to traffic by 1985. In 1989, construction concluded on I-88 with the opening of the final portion of I-88 between I-81 in Chenango and NY 7 in Chenango Bridge. In 1999 NYSDOT, the Federal Highway Administration (FHWA) and the New York State Thruway Authority (NYSTA) discussed redesignating the Berkshire Connector as I-90 and redesignating the nontoll part of I-90 from Thruway exit 24 to exit B1 on the Berkshire Connector as I-88. The section of the Thruway between exits 25 and 24 would then be codesignated as I-90 and I-88. This was never implemented. 2006 flood As a result of the June 2006 flooding in Upstate New York and Northeastern Pennsylvania, Carrs Creek washed out a section of I-88 southwest of Unadilla on June 28. Around 6:20 am, two trucks from different directions drove into the chasm, apparently unaware of it, killing both
