Linkou A Northbound Exit Ramp and Linkou B Northbound Entrance Ramp to Close October 29–30 for Construction

Guishan District, in Taoyuan City - The First Engineering Branch Office of the Freeway Bureau is carrying out “the Freeway 1 Linkou Interchange Improvement Project”. One of two newly constructed grade-separated vehicular box culverts serving the northbound section of the interchange is nearing completion. Once opened, traffic using the Linkou A northbound exit ramp and Linkou B northbound entrance ramp will be diverted through the new box culvert.
According to the construction team, The closures are scheduled from 10 p.m. to 6 a.m. the following morning, October 29–30, 2026 ( Thursday through Friday). Before the new route opens to traffic, both ramps will be closed for two consecutive nights to connect the new box culvert lanes to the existing ramps. The work includes subgrade construction, asphalt concrete (AC) paving, and road marking.
Beginning at 6 a.m. on October 31 (Saturday), traffic using the Linkou A northbound exit ramp and Linkou B northbound entrance ramp will be redirected through the new vehicular box culvert. Motorists are advised to follow the traffic signs and detour directions (See Figure 2).
