Although the section of Hashimoto Road between the Hashimoto-higashi Interchange and the Hashimoto Interchange had also been scheduled to open in 2006, many cracks were discovered in the Tarui elevated bridge, which had been completed in 2002; therefore, the Ministry of Land, Infrastructure, Transport and Tourism decided to demolish it and rebuild its beams (seven continuous spans) but later accepted the contractor's new plan for repairs and follow-up examinations of the effect, and this section was finally opened on August 2, 2007.
また、橋本道路の橋本東IC～橋本ICも2006年内に開通の予定であったが、2002（平成14）年に完成した垂井高架橋にひび割れが多数発見され、国土交通省は橋桁（7径間連続）の取り壊しと再築を決定したが、施工業者の補修と効果監視の新提案が承認され、同区間は2007年8月2日に開通した。
