Interstate 990

I-990 northbound from the Amherst pedestrian bridge

I-990 begins at a semi-directional T interchange (exit 4) with I-290 (Youngmann Expressway) in the Buffalo suburb of Amherst. After leaving the interchange, I-990, known as the Lockport Expressway, proceeds northward along the western edge of the University at Buffalo's Amherst Campus as a four-lane divided expressway. It generally parallels Sweet Home Road (unsigned NY 952T) to exit 1, a northbound-only interchange providing access to Audubon Parkway by way of a two-lane connector to the campus. From here, I-990 gradually bends northeastward, leaving the vicinity of the campus and entering a partial cloverleaf interchange (exit 2) connecting to Sweet Home Road.[5]

The Interstate Highway continues to turn to the northeast as it heads away from exit 2, crossing over Ellicott Creek and Dodge Road (County Route 45). I-990 expands to six lanes just as it enters the nearby exit 3, which connects to Dodge Road and the northern end of the Audubon Parkway. The freeway briefly runs eastward from the junction, paralleling Dodge Road into the hamlet of Getzville, where the expressway passes over NY 270 (Campbell Boulevard). Just after the NY 270 crossing, I-990 bends northward once again and enters exit 4, a diamond interchange with North French Road (CR 299).[5]

Past North French Road, I-990 bends back to the northeast, crossing Hopkins Road (CR 87) as it approaches an at-grade intersection with NY 263 (Millersport Highway). The junction serves as I-990's exit 5 and its northern terminus. Traffic approaching the junction on northbound I-990 is diverted onto what was intended to be a single-lane exit ramp leading to NY 263. A small stub of highway exists east of the exit gore.[5]

On October 30, 1968, the New York State Department of Transportation (NYSDOT) nominated 20 proposed highways to be added to the Interstate Highway System as part of a 1,500-mile (2,400 km) nationwide system expansion authorized by the Federal-Aid Highway Act of 1968. One of the submitted roads was the Lockport Expressway, a 12-mile (19 km), $22-million limited-access highway extending in a northeast–southwest direction between I-290 north of Buffalo and a proposed Niagara Falls–Rochester freeway near Lockport.[6] When the city of Niagara Falls released its Regional Highway Plan for the Buffalo–Niagara Falls area in 1971, the Niagara Falls–Rochester highway was scrapped; as a result, the north end of the Lockport Expressway was moved to a point on NY 31 east of Lockport. In between I-290 and NY 31, the highway would intersect the proposed Belt Expressway and NY 78 (Transit Road).[7]

While the outer belt proposal was mostly dropped, the plans to build the Lockport Expressway gained traction in January 1979 when the 4.2-mile (6.8 km) portion between I-290 and North French Road was added to the Interstate Highway System and designated as I-990.[2][8] The remainder of the original 12-mile (19 km) route was excluded due to a lack of funding.[9] Construction began in 1980 on the part south of Sweet Home Road,[3][9] and the highway was opened to traffic by 1985. The section leading northeast to North French Road was built during the mid-1980s[3][4] and completed by 1990.[10] In 1986, NYSDOT began to evaluate ways to improve the highways surrounding the northern terminus of I-990. One of the potential options was an extension of the freeway to NY 263 (Millersport Highway) southwest of Lockport.[11] This option was ultimately selected, and the new section of the freeway was opened to traffic on December 21, 1990.[12] It was officially added to I-990 on October 22, 1993.[13]

In June 2013, I-990 was renamed from the Lockport Expressway to the Staff Sergeant William R. Wilson III Memorial Highway. This is in honor of his contributions to the US military, which included training Afghan soldiers and police to take over the country's security. Staff Sergeant Wilson also served two combat deployments to Iraq as part of Operation Iraqi Freedom. As a result, he was posthumously awarded the Bronze Star Medal and Purple Heart. He also received the National Defense Service Medal, Iraq Campaign Medal, and the Afghanistan Campaign Medal, as well as the Army Service Ribbon and Overseas Service Ribbon. The bill to rename I-990 was sponsored by State Senator Michael Ranzenhofer and Assemblyman Raymond Walter. Signage is now displayed at each terminus showing the new name.[14]

The entire route is in Amherst, Erie County.
