秦直道 / Qin Straight Road
秦直道 / Qin Straight Road enters the wiki through Qinji 125-1 as the road 秦始皇 orders 蒙恬 to build from Yunyang to Jiuyuan in 212 BCE. The episode stresses its length, construction difficulty, and unfinished condition over multiple years.
This page keeps Qin Straight Road distinct from 驰道. Both belong to Qin imperial infrastructure, but the episode presents the straight road as a specific northern-route project tied to Meng Tian and late Qin mobilization rather than the broader road system described in Qinji 121.
In the Qinji 125-1 synthesis, Qin Straight Road is one piece of 帝国工程过载 beside 阿房宫, 秦始皇陵, palace networks, and forced relocations. The state that continues campaigning and building after unification also has to keep finding labor for monumental routes.
《资治通鉴·秦纪》127-2｜李斯为啥不帮英明的扶苏 gives the road a succession-crisis use. After the forged order kills 扶苏 and fails to make 蒙恬 die, the convoy reaches Jiuyuan and then returns rapidly toward 咸阳 through Qin Straight Road, allowing 李斯, 赵高, and 胡亥 to delay public mourning until the accession result is ready.
《资治通鉴·秦纪》127-3｜海外回归一批竹简 揭开胡亥立帝之谜！ preserves that timing function in the traditional branch while complicating the accession mechanism through 《赵正书》. The road still helps the convoy turn a hidden death into a controlled public announcement, but the new source asks whether the heir decision itself was already made before the return.
Qinji 127-4 changes the road’s function from logistics to moral evidence. The episode cites 扬雄, 司马光, and 司马迁 to argue that 蒙恬’s work on the straight road and related long-wall/barrier projects makes his loyal death morally complicated rather than purely heroic.
Key Claims
- The source dates the road order to Qin Shi Huang’s thirty-fifth year, 212 BCE.
- Meng Tian is named as the official in charge.
- The road is presented as very long and difficult enough to remain incomplete for years.
- It belongs beside late Qin palace and mausoleum work as a case of heavy construction mobilization.
- Qinji 127-2 uses the road as the rapid return route that helps convert hidden death into controlled succession announcement.
- Qinji 127-3 keeps the road as a return-route timing device while separating it from the unresolved question of forged versus deathbed accession.
- Qinji 127-4 makes the road part of Meng Tian’s moral liability for harsh Qin labor mobilization.
Connections
- 嬴政 / 秦始皇, 秦国, and 蒙恬 - ruler, regime, and construction commander.
- 驰道 - related but broader road-system page.
- 统一后战争惯性 - structural context for late Qin frontier and military-mobility demands.
- 帝国工程过载 - labor and project-load frame.
- 阿房宫 and 秦始皇陵 - parallel late Qin mega-projects.
- 秘不发丧式过渡控制, 伪诏继位政变, 扶苏, 赵高, and 胡亥 / 秦二世 - Qinji 127-2 return route after the hidden-death coup.
- Qinji 127-3, 《赵正书》, and 临终就近立储 - source conflict over whether the route followed a forged or deathbed-selected accession.
- Qinji 127-4, 扬雄, 司马光, 司马迁, and 忠臣事暴政的罪责 - later moral judgment on Meng Tian’s construction role.
