交通部公路局北區養護工程分局辦理北寧路邊坡修復工程。台2線北寧路通往潮境公園的平浪橋頭山壁，6月3日下午發生大面積山壁崩塌，經連日搶修已開放民眾通行，但邊波修復作業仍持續進行中，謝國樑今早也到現場勘查，表示目前施工情況一切正常，呼籲行經北寧路的用路人謹慎駕駛、小心慢行，並配合相關管制措施。
基隆市長謝國樑親自到場了解工程情況，並呼籲用路人行經該路段配合管制或提前改道。Log Periodic Antenna (LPDA)
Log Periodic Antenna (LPDA)公路局北區養護工程分局表示，該路段為避免施工中零星落石影響行進中車輛，今明兩天9時至16時30分將視情況雙向封閉，每次封閉不超過15分鐘，提醒往來基隆、瑞濱間用路人配合交通管制，敬請隨時注意路況廣播或資訊可變看板(CMS)顯示之交通管制訊息，或提前改道改行調和街、102線（逢甲路）接台2丁線，避開施工路段。

The Log Periodic Antenna as known as LPDA is a wideband directional antenna that provides gain and directivity combined over a wide band of frequencies.
Both Log-Periodic Antennas and Yagi antennas are high gain directional antennas. The main difference between these antennas is that Log-Periodic Antennas support wider frequency bandwidths and are physically much larger than Yagi antennas.
The log-periodic dipole array typical VSWR is 2:1 and operates over a much wider bandwidth and will have a lower gain for an equivalent number of elements.
With this level of performance, it is ideal for many applications, although a log-periodic antenna will be much larger than a Yagi of an equivalent gain.
