Yongin city announced Thursday that it has temporarily opened Bogae-Wonsam Road as a four-lane highway, connecting the Gajaewol intersection on National Route 17 in Wonsam-myeon, Cheoin-gu, to the Yongin Semiconductor Cluster.
The road expansion was pursued to proactively address the sharp increase in traffic volume resulting from full-scale industrial complex development, including the groundbreaking of SK hynix's (000660.KS) semiconductor fab.
The city has invested 43.3 billion won ($32 million) since May 22 last year to widen the 1.88-kilometer section from Gajaewol-ri to Dokseong-ri in Wonsam-myeon, Cheoin-gu, from two lanes to four lanes.
All sections except the Gajaewol 1 Bridge have been temporarily opened first. The entire route including the bridge section is scheduled for official opening on May 21, 2026.
The city expects the temporary opening to improve traffic flow, as the narrow road width had previously caused severe congestion with large construction vehicles mixing with commuter traffic. The road directly connects to the recently opened South Yongin interchange on the Sejong-Pocheon Expressway, which is expected to positively impact logistics and transportation for the Yongin Semiconductor Cluster general industrial complex.
"Citizens experienced significant inconvenience due to chronic congestion when the road was only two lanes, but this temporary opening now allows for comfortable and safe road use," Yongin Mayor Lee Sang-il said. "We will complete the remaining work without delay to actively support the successful development of the semiconductor cluster."
