'''National Freeway 3''' ({{zh|t=國道三號|hp=Guódào sān hào}}), also known as '''Formosa Freeway''' ({{zh|t=福爾摩沙高速公路|hp=Fúěrmóshā gāosù gōnglù}}), is a [[freeway]] in [[Taiwan]]. It is the second north–south freeway in Taiwan, beginning in [[Keelung City]] at Jijin Interchange on the provincial highway 2 (Jijin Road) and ending in [[Linbian|Linbian, Pingtung]] on the provincial highway 17. It is the longest freeway in Taiwan with a total length of {{convert|431.5|km|abbr=on}}. The freeway also has a spur route, [[National Freeway 3A|Freeway 3A]].

The highway has 58 interchanges, 15 junctions, 7 service areas and 3 rest areas en route.<ref>{{Cite web |date=2021-07-02 |title=Freeway facilities (interchanges, service areas) |url=https://www.freeway.gov.tw/english/Publish.aspx?cnid=1914&p=4608 |url-status=live |archive-url=https://web.archive.org/web/20221108081753/https://www.freeway.gov.tw/english/Publish.aspx?cnid=1914&p=4608 |archive-date=2022-11-08 |access-date=2022-11-08 |website=[[Freeway Bureau|Freeway Bureau, MOTC]] |language=en}}</ref> Aside from the 58 public interchanges, there are also some interchanges reserved for governmental usage.

==Route Description==
This freeway mostly serves as a [[bypass (road)|bypass]] to major cities in [[Western taiwan|Western Taiwan]], traveling through suburban and rural areas. However, Freeway 3 is also the primary freeway in the counties of [[Nantou County|Nantou]] and [[Pingtung County|Pingtung]], as well as the first ever being built in these counties. Various expressways and east–west freeways link Freeway 3 with urban areas typically served by [[National Freeway 1|Freeway 1]]. The purposes of this freeway are to increase economic development in the rural area and to relieve congestion along Freeway 1.

The freeway begins at an intersection with [[Provincial Highway 2 (Taiwan)|Provincial Highway 2]] ({{Lang-zh|c=|s=|t=臺二線|p=}}) and Provincial Highway 2F ({{Lang-zh|c=|s=|t=臺二己線|p=}}) in [[Keelung]]. Highway 2F, also known as Port of Keelung Western Connector ({{Lang-zh|c=|s=|t=基隆港西岸聯外道路|p=}}), is an elevated road that connects the [[Port of Keelung]] with Freeway 3. The freeway travels in a northeast–southwest direction through the western part of Keelung before intersecting Freeway 1 in [[Xizhi District|Xizhi]]. The freeway then travels along the mountains of [[New Taipei City]] and [[Taipei]], bypassing the southeastern and southern edge of the Taipei metropolitan area. Connections to downtown Taipei are available through Huandong Blvd ({{Lang-zh|c=|s=|t=環東大道|p=}}) in [[Nangang District, Taipei|Nangang]] and [[National freeway 3A|Freeway 3A]] in [[Wenshan District|Wenshan]]. In Nangang, the freeway intersects [[National Freeway 5]], which travels through the [[Xueshan Range]] before reaching [[Yilan County, Taiwan|Yilan County]] in [[Eastern Taiwan]]. In [[Yingge District|Yingge]], the freeway meets [[National Freeway 2]] which provides connections to downtown [[Taoyuan, Taiwan|Taoyuan]] as well as Taipei's main international airport, [[Taoyuan International Airport]]. In Taoyuan, the freeway is mostly parallel to [[Provincial Highway 3 (Taiwan)|Provincial Highway 3]], traveling through the mountainous areas of the city. As the freeway enters [[Hsinchu County]] it turns to a slightly east–west direction before intersecting Freeway 1 for the second time at the border of Hsinchu county and [[Hsinchu]] city. This stretch of the freeway is also known as the Northern Second Freeway ({{Lang-zh|c=|s=|t=北部第二高速公路, 北二高|p=}}).

In [[Miaoli County]] the freeway mostly parallels Freeway 1 and [[Provincial Highway 61 (Taiwan)|Provincial Highway 61]] (also known as West Coast expressway, {{Lang-zh|c=|s=|t=西濱快速道路|p=}}) all the way to [[Taichung]]. In Taichung, the freeway intersects with [[National Freeway 4]]  just north of [[Taichung International Airport]]. The stretch from Freeway 4 to [[Provincial Highway 74 (Taiwan)|Provincial Highway 74]] (Kuaiguan-Wufeng expressway, {{Lang-zh|c=|s=|t=快官霧峰線|p=}}) forms the western and southern portion of the Taichung Beltway ({{Lang-zh|c=|s=|t=臺中環線|p=}}). After entering [[Changhua County]] the freeway turns into a northwest–southeast direction heading towards [[Nantou County]], intersecting Freeway 1 for the third and final time in [[Changhua]]. Before entering [[Nantou City]] the freeway meets [[National Freeway 6]], which connects to the mountainous town of [[Puli, Nantou|Puli]] and the [[Central Mountain Range]]. In Nantou, the freeway mostly travels in a north–south direction before exiting to [[Yunlin County]], where it travels in a slight northeast–southwest direction again along Yunlin and parallels Freeway 1. This stretch of the freeway from Hsinchu to the intersection of [[Provincial Highway 78 (Taiwan)]] in [[Gukeng, Yunlin]] is also known as the Central Second Highway ({{Lang-zh|c=|s=|t=中部第二高速公路, 中二高|p=}}).

The highway continues to parallel Freeway 1 as it travels along the eastern parts of [[Chiayi County]] and [[Tainan]]. Provincinal highways [[Provincial Highway 82 (Taiwan)|82]], [[Provincial Highway 84 (Taiwan)|84]], and [[Provincial Highway 86 (Taiwan)|86]] as well as [[National Freeway 8]] provide connections between Freeways 1 and 3. In [[Kaohsiung]] the freeway bypasses the downtown area and travels along the mountainous rural districts. Connections to downtown and [[Kaohsiung International Airport]] are available through [[National Freeway 10]], which the freeway intersects in the rural district of [[Yanchao District|Yanchao]], as well as [[Provincial Highway 88 (Taiwan)|Provincial Highway 88]] in the urban township of [[Chaozhou, Pingtung|Chaozhou]] in [[Pingtung County]]. After passing though the intersection with Freeway 10, the freeway enters Pingtung and ends in Dapengwan National Scenic Area in the rural township of [[Linbian, Pingtung|Linbian]]. The southern stretch of the highway is known as the Southern Second Highway ({{Lang-zh|c=|s=|t=南部第二高速公路, 南二高|p=}}).

==Naming==
Freeways in Taiwan are officially coded "Freeways" with their respective numbers. By this principle, national freeway 3 is coded '''Freeway No. 3''' ({{Lang|zh-tw|國道三號}}) in official documents or on road signs. Besides the numeric name, on November 1, 2004, it was named the '''Formosa Freeway''' ({{Lang|zh-tw|福爾摩沙高速公路}}) in a naming competition; however, its old alias '''Second Freeway''' ({{Lang|zh-tw|第二高速公路}} or {{Lang|zh-tw|二高}}) is more popular among the road users.

==History==
The original plan was only intended to build a second freeway between [[Taipei]] and [[Hsinchu]]. The construction began in 1987. Tucheng IC - Sanying IC was opened in January 1993, followed by Zhonghe IC to Hsinchu SIC in August 1993. Extension from Hsinchu SIC to Xiangshan IC was finished in February 1996. In March 1996, Xizhi SIC - Muzha IC was opened. The final phase of the north section was Muzha IC. - Zhonghe IC, which was completed in August 1997. The extension between Xizhi SIC and Jijin IC completed in August 2000.

The construction of the freeway south of [[Hsinchu City]] began in 1993. In February 2000, Xinhua JCT. - Jiuru IC. was open for the traffic. It was followed by Douliu IC - Xinhua JCT. In November 2001, Xiangshan IC. - Zhunan IC in December 2001, Zhunan IC - Houlong IC in May 2002, Caotun IC - Douliu IC in June 2002, Zhonggang SIC - Longjing IC in October 2002, and Houlong IC - Zhonggang JCT., Kuaiguan IC - Caotun IC in January 2003. The entire project was completed in January 2004 when Longjing IC - Kuaiguan IC was opened.

== 2010 landslide ==
On 25 April 2010, a landslide occurred on a segment near [[Xizhi]]. A large amount of dirt buried both directions of the freeway. Four cars were buried under the debris, killing four people.<ref>{{cite news|url=http://www.cna.com.tw/SearchNews/doDetail.aspx?id=201004280068&q=%22%e5%8c%97%e4%ba%8c%e9%ab%98%e8%b5%b0%e5%b1%b1+4%e4%ba%ba%e7%bd%b9%e9%9b%a3%22|script-title=zh:北二高走山 4人罹難|date=2010-04-28|publisher=[[Central News Agency (Republic of China)|Central News Agency]]|language=zh}}</ref> Bad hillside anchoring was blamed as a possible cause, as it had not been raining at the time of the collapse and an earthquake was not registered.

Repairs to the freeway were completed on 19 June 2010 and normal traffic flow restored.<ref>{{cite news|url=http://www.freeway.gov.tw/Publish.aspx?cnid=193&p=2039|script-title=zh:國道3號3.1公里崩塌路段6月19日12時恢復主線雙向3車道通行|publisher=Taiwan Area National Freeway Bureau|date=2010-06-18|language=zh}}</ref>
