Question: How many miles long does KY 1319 (Kings Church Road) measure? Passage 1:Ma Dai is a character in the 14th-century historical novel Romance of the Three Kingdoms, which romanticises the historical events and figures of the late Eastern Han dynasty and Three Kingdoms period. In the novel, he follows Ma Teng to the capital on a summon from Cao Cao, and survives when Ma Teng and his sons are killed by Cao Cao's men in a trap. He joins his cousin Ma Chao in the Battle of Tong Pass against Cao Cao, and accompanies Ma Chao when the latter is defeated and has to seek refuge under Zhang Lu of Hanzhong. He follows Ma Chao and comes to serve Liu Bei when his cousin defects to Liu Bei's side during the takeover of Yi Province. Ma Dai participates actively in southern campaign against the Nanman and the Northern Expeditions against the rival state of Cao Wei. After Zhuge Liang's death, the Shu general Wei Yan rebels, and Ma Dai pretends to support him but kills him later.
Passage 2:The US Seventh Fleet patrolled the strait both to protect the island from Communist assault and to prevent the Taiwanese from beginning international incidents through assaults on the mainland expected to be fruitless. Chinese assaults led to "Taiwan Strait Crises" in 1954 & 1955 and 1958 that were ended by threat of war with the US; Chiang Kai-shek's plans for China's reconquest were mostly abandoned after a failed landing at Magong in 1965. Hopes for immediate military reunification of China gave way to a One-China Policy espoused by both Chinas and the international community; most international recognition switched from the Republic of China to the People's Republic of China in the 1970s. A third Taiwan Strait Crisis occurred in 1995 & 1996 and cross-Strait relations remain strained, with a strengthening PRC economy also strengthening its military and deployments on the straits.
Passage 3:Kentucky Route 1531 is a rural secondary highway that begins in northeastern Bullitt County and ends in northwestern Shelby County, but the route spends almost all of its length in the city of Louisville in eastern Jefferson County. The highway begins at KY 1319 (Kings Church Road) near Whitfield. KY 1531 heads northwest along Dawson Hill Road then turns northeast onto Routt Road to enter the city of Louisville and Jefferson County. The highway crosses Wheelers Run and Back Run and meets the eastern end of KY 1819 (Brush Run Road) south of the Routt neighborhood of Louisville. KY 1531 follows Sheckels Run to its crossing of Cane Run and reaches KY 155 (Taylorsville Lake Road) south of Fisherville. The highway runs concurrently with KY 155 northwest across Floyds Fork of the Salt River to KY 148 (Taylorsville Road), with which the route heads east through Fisherville and across Floyds Fork again.
