Xiwei Bridge ({{lang-zh|t=溪尾大橋|p=Xīwěi Dàqiáo}}) is a bridge across the Dadu River in Wuri District, Taichung City, Taiwan. The bridge connects Taichung with Xiwei Village, a pene-exclave on the southwest bank of the river. Another bridge, known as the Xiwei Second Bridge ({{lang-zh|t=溪尾二橋}}), serves as the road's westward extension into Fenyuan Township, Changhua County.
History
The Dadu River has historically been the boundary between Taichung and Changhua. On August 7, 1959, a major flood changed the course of the river and isolated Xiwei Village from the rest of Taichung. While there are multiple roads connecting Xiwei to Changhua County, there was no direct method for Xiwei residents to reach Taichung.{{cite news|author1=李鴻典|date=November 22, 2016|title=台中溪尾大橋通車！這地方不再是孤島|language=zh-tw|agency=SET News|url=https://www.setn.com/News.aspx?NewsID=200477|access-date=June 15, 2021}}

On the Xiwei end, the road stopped at a T-intersection with the one-lane, {{convert|2.5|m|abbr=on}} Qingguang Road, which led to frequent accidents as cars tried to pass each other in the narrow space. Three passing areas were built in 2017 as a temporary solution while the second bridge was under construction.{{cite news|author1=邱植培|author2=彭煥羣|date=April 13, 2019|title=烏日溪尾大橋車多 聯外道卻是狹窄農路|language=zh-tw|agency=PTS|location=Taichung|url=https://news.pts.org.tw/article/429751|access-date=June 15, 2021}}{{cite news|author1=蘇金鳳|date=March 7, 2018|title=烏日下溪尾大橋轉慶光路難會車 議員要求改善|language=zh-tw|agency=Liberty Times|url=https://news.ltn.com.tw/news/life/breakingnews/2358541|access-date=June 15, 2021}}
