僅剩零星內容 All that is left are some scraps:
台灣三角點 TWD67 座標表 (TWD67 Taiwan Triangulation Points' Coordinates)
我很好奇,台中僑光商專周圍有一個直徑一公里的圓形小馬路, Odd, on maps from the 1980's there is traces of a 1 km. diameter circular road centered at 中心點在 TWD67 213230 mE, 2676040 mN, (north of Fengjia Univ., Taizhong). 很多政府的圖看得到其北端,但快被都市計劃磨滅。那是什麼東西?國際上 看到大規模圓形東西為核子加速器… Traces of an old cyclotron?
My friend guesses it might be a 朋友猜可能是個 high frequency direction finder, like the ones in 林口湖北村 Linkou, TWD67: 2776.5 km N 289 km E, used in cooperation with the USA in coordination with others in Asia to triangulate signals from China. However the diameter of the largest Linkou one is only 1/3 km.
大雅交流道沒建在原中清路正上方,而另繞旁路,看地圖令我很好奇, 不是只增加紅路燈?
Why isn't Taizhong's Daya Interchange on Zhongqing Rd. but instead on an extra side road? Looks so curious on a map. Doesn't that just increase the number of red lights?
黃立夫說是原水湳機場跑道衝突。
網友 e0165 則試算水湳機場跑道的限建範圍及高度:
因交流道距跑道約900米, 所以限建高度=900∕50=18米, 以一般高速公路路堤高度約10米以下, 所以應該沒有影響(以機場跟高速公路地面同高估計)
限建範圍是梯形,所以交流道往北移還是在限建範圍。
所以我認為原中清路正上方建築物太多了, 所以交流道往北移。
