Hawaii Route 197

Hawaii Route 197 currently is a 1.2 mile partially complete state highway located on the Big Island near Kona International Airport. The corridor as presently constructed originates at Hawaii Route 19 and follows Kealakehe Parkway east to a dead-end at Keanalehu Drive. The corridor of Hawaii Route 197 has a proposed extension which would terminate 1.9 miles to the east at Hawaii Route 190 and connect with the great Mamalahoa Highway.

Part 1; the history of Hawaii Route 197

The planned corridor of Hawaii Route 197 (Kealakehe Parkway) is 3.1 miles in scale and would connect Hawaii Route 19 (Queen Kaahumanu Highway) near Kona International Airport east to Hawaii Route 190 (Mamalahoa Highway). The intent of the corridor is to replace the functionally obsolete Palani Drive (Hawaii Route 190) as the primary connector to Mamalahoa Highway.

The adoption of Hawaii Route 197 into the state highway system is not fully clear, but likely came during the 1980s. The highway appears complete from Hawaii Route 19 east to Keanalehu Drive (approximately 1.2-miles) on the 1998 United States Geological Survey map (courtesy historicaerials.com).

The remaining unconstructed portion of Hawaii Route 197 from Keanalehu Drive east to Hawaii Route 190/Mamalahoa Highway on the current Hawaii Department of Transportation log for the Big Island. The corridor is planned to tie into Mamalahoa Highway south the junction of Hawaii Route 190 and Hawaii County Route 180. The status of the unconstructed portion of Hawaii Route 197 is unclear as it remained unaltered on the 2012 state of Hawaii Federal-Aid System logs.

Part 2; a drive on Hawaii Route 197

Hawaii Route 197 eastbound begins at the intersection of Hawaii Route 19 at Kealakehe Parkway. There are no reassurance shields altering traffic to the presence of Hawaii Route 197.

Hawaii Route 197 ascends eastbound to a dead-end at Keanalehu Drive. The corridor has no Hawaii Route 197 signage or mile markers. Overhead the peak of Hualalai can be seen looking in the distance.

The 1915-era Teilman Bridge (the only known Concrete Pony Truss Bridge in California)

The Teilman Bridge is a semi-abandoned structure over Fresno Slough west of Burrell siding near the intersection of Elkhorn Avenue and Elkhorn Grade. This structure is the only known Concrete Pony Truss Bridge constructed in California and was designed by Ingvart Teilman. Teilman's Bridge would open in late 1915 when the Elkhorn Grade was the primary road between Fresno and Coalinga. The structure would be replaced in 1991 but was left standing as it carries pipelines over Fresno Slough. Part 1; the history of the Teilman Bridge In the early Twentieth Century the most direct highway between Fresno and Coalinga followed the Elkhorn Grade. The Elkhorn Grade began at Fresno Slough a short distance west of Burrell siding. From Fresno Slough the Elkhorn Grade followed a generally southwestern course through San Joaquin Valley into the Kettleman Hills towards Coalinga. The Elkhorn Grade can be seen on the 1914 C.F. Weber map of Fresno Coun...

The Dummy Lights of New York

A relic of the early days of motoring, dummy lights were traffic lights that were placed in the middle of a street intersection. In those early days, traffic shuffled through busy intersections with the help of a police officer who stood on top of a pedestal. As technology improved and electric traffic signals became commonplace, they were also originally positioned on a platform at the center of the intersection. Those traffic signals became known as " dummy lights " and were common until traffic lights were moved onto wires and poles that crossed above the intersection. In New York State, only a handful of these dummy lights exist. The dummy lights are found in the Hudson Valley towns of Beacon and Croton-on-Hudson, plus there is an ongoing tug of war in Canajoharie in the Mohawk Valley, where their dummy light has been knocked down and replaced a few times. The dummy light in Canajoharie is currently...

Prunedale Road (Monterey County)

Prunedale Road is a short 2.6-mile-long frontage corridor of US Route 101 in the namesake Monterey County community of Prunedale. Prior to 1932 US Route 101 bypassed Prunedale in favor of the San Juan Grade to the east. Prunedale Road along with nearby Moro Road served as an alternative connecting highway between Salinas and San Juan Bautista. Following the realignment of US Route 101 onto the Prunedale Cutoff the former through route along Prunedale Road would be rendered as a western frontage. Part 1; the history of Prunedale Road Prunedale Road is located in and is named after the Monterey County community of Prunedale. Said community was founded near the junction of San Migeul Canyon, Langley Canyon and Echo Valley. Watsonville settler Charles Langley (namesake of Langley Canyon) was one of the prominent early community settlers. The Prunedale Post Office would open for the first time in 1894 but would close by 1908. Early agricu...
