'''National Freeway 2''' ({{zh|t=國道二號}}) is a connector [[freeway]] in [[Taiwan]] that traverses the [[Special municipality (Taiwan)|special municipalities]] of [[Taoyuan, Taiwan|Taoyuan City]] and [[New Taipei City]]. The freeway begins at [[Taiwan Taoyuan International Airport]] in [[Dayuan District]], [[Taoyuan City]], traveling in a northwest–southeast direction along northern Taoyuan City and ends in [[Yingge District|Yingge]] at the junction with [[National Freeway 3]]. It is {{cvt|20.4|km}} long.

The freeway was initially signed as National Freeway 1A ({{zh|t=國道一甲|c=|s=|p=}}) from 1980 to 1997 before the highway was extended to its current eastern terminus in Yingge. The initial segment of the freeway, between Taipei Taoyuan International Airport and [[National Freeway 1]] is commonly known as Airport Connector ({{Lang-zh|c=|s=|t=機場支線|p=}}), while the segment between National Freeway 1 and National Freeway 3 is a part of the Taoyuan Ring Road ({{Zh|c=|s=|t=桃園環線|p=}}).

The airport is an important connector that links the international airport and [[Taoyuan HSR station]] with National Freeways 1 and 3. Like all east–west freeways in Taiwan, there are no tolls traveling along the entire freeway.

== Route description ==
National Freeway 2 begins as an 8-lane highway (4-lane in each direction) at Taiwan Taoyuan International Airport in Dayuan. The freeway then goes through the suburban districts of [[Dayuan District|Dayuan]] and [[Luzhu District, Taoyuan|Luzhu (Nankan)]] before reaching National Freeway 1 in [[Taoyuan District]] (the former urban area of Taoyuan). In Luzhu, the freeway intersects [[Provincial Highway 31 (Taiwan)|Provincial Highway 31]], which provides access to the nearby [[Taoyuan HSR station]]. After the interchange with National Freeway 1, the freeway continues as a 6-lane highway and intersects Daxing West Road ({{Zh|c=|s=|t=大興西路|p=}}) in the southwestern edge of Taoyuan district before entering [[Bade District|Bade]]. After the interchange with County Road 110B, the freeway enters [[New Taipei City]] for a short stretch before its terminus at National Freeway 3 in [[Yingge District|Yingge]].

The entire freeway has a speed limit of 100&nbsp;km/h, except for the stretch between the airport and Dayuan interchange (70&nbsp;km/h for westbound traffic to the airport, and 90&nbsp;km/h for eastbound traffic from the airport).

==History==
The {{cvt|8.6|km|mi|adj=on}} section of National Freeway 2 between the Taiwan Taoyuan International Airport (previously named as Chiang Kai-shek International Airport) and National Freeway 1 was opened to traffic in November 1980 to provide faster connections to the main international airport of Taiwan. The freeway was originated designated as National Freeway 1A, a branch of National Freeway 1. Initially a 4-lane highway, this section was eventually widened to 8 lanes in 2011 to alleviate traffic congestion.

When the road was extended to Yingge to connect the newly constructed National Freeway 3 in 1997, the entire route was renumbered as National Freeway 2. In January 2006 Dazhu interchange was built to provide an easy access to the newly constructed [[Taoyuan HSR station]]. In April 2013, an interchange to the Wugu-Yangmei elevated road ({{Lang-zh|c=|s=|t=五股楊梅高架道路|p=}}), a local bypass to National Freeway 1, was built. The interchange allows westbound entrance for traffic to the airport and eastbound exit for traffic from the airport.

On January 8, 2023, a spur route of the highway, known as Freeway 2A, connecting Freeway 2 and [[Provincial Highway 15 (Taiwan)|Provincial Highway 15]], opened.
