Daejeon Metropolitan City will launch full-scale tram construction across all 14 sections of Metro Line 2 starting in March, beginning with main construction work on the remaining five zones.
The remaining zones set to begin construction are Zones 3, 4, 5, 9, and 14.
As construction will proceed simultaneously across all sections, the city plans to implement measures to minimize traffic disruptions and ensure public safety amid expected congestion.
Zones 3 (Jungni 3-ga to Sujeong Town Apartment) and 4 (Sujeong Town Apartment to Government Complex) will see partial closure of one lane toward the agricultural and fisheries market. Zone 5 (Government Complex Station to National Science Museum), which encompasses university and research district areas, will have two lanes closed on both sidewalk sides near Seonsa Historic Site intersection.
Zone 9 (Jinjam intersection to Konyang University Hospital intersection), a high-traffic area, will reduce operations from 10 to 8 lanes by closing two lanes toward Jinjam. Zone 14 (Donga Technical High School intersection) will also see two lanes closed from Gayang intersection to Daeju Park Ville intersection.
The city will apply a six-phase construction system to minimize road occupation, including structural work on bridges and underground sections, sidewalk reduction and setback, interior and exterior tram line construction, and final lane adjustments at stations and intersections.
The city will also coordinate closely with local police to temporarily suspend or abolish dedicated bus lanes in construction zones to distribute traffic flow. High-visibility guidance signs and safety fences will be installed preemptively to prevent accidents.
Additionally, a three-stage customized traffic management plan will be implemented progressively. Stage 1, currently in effect, focuses on intensive bus dispatching, traffic signal optimization, and lane adjustments. If traffic speeds fall below 20 km/h (Stage 2), highway toll subsidies for pilot sections will be introduced. If speeds drop below 15 km/h (Stage 3), the city will expand toll subsidies citywide and implement stronger traffic demand management policies, including an odd-even driving system for public institution vehicles.
Choi Won-seok, Director General of Urban Railway Construction Bureau, said, "Traffic inconveniences are inevitable during tram construction, but this is an essential process toward becoming a better public transit-centered city. We ask for citizens' active cooperation in using public transportation and alternative routes."
