It is the second expressway to be opened in the country and is {{convert|38.4|km}} in length. The expressway has played an important role in alleviating ground-level road traffic in Bangkok.<ref name=":0">{{Cite web |title=ทางพิเศษศรีรัช |url=https://www.exat.co.th/project/%E0%B8%97%E0%B8%B2%E0%B8%87%E0%B8%9E%E0%B8%B4%E0%B9%80%E0%B8%A8%E0%B8%A9%E0%B8%A8%E0%B8%A3%E0%B8%B5%E0%B8%A3%E0%B8%B1%E0%B8%8A/ |website=EXAT}}</ref>
[[Si Rat MRT station]] on the [[Pink Line (Bangkok)|Pink Line]] is named after the expressway. == History == Due to a significant increase in road traffic in the [[Bangkok Metropolitan Region]], and after the [[Chaloem Maha Nakhon Expressway]] was opened, a second expressway was proposed in order to alleviate the increased traffic. The Expressway Authority of Thailand (EXAT) assigned [[Bangkok Expressway and Metro|Bangkok Expressway and Metro (BEM)]] to construct this expressway and a contract was signed on 22 December 1988.
Expressway construction was opened in four stages, named A to D. Section A between Pracha Chuen–Phaya Thai–Phra Ram 9 was opened on 2 September 1993 along with Section C between Phra Ram 9–Srinagarindra which opened on the same day. Section B between Phaya Thai–Bang Khlo opened on 6 October 1996. Section D between Pracha Chuen–Chaeng Watthana opened on 1 April 2000.<ref name=":0" />
According to an official EXAT annual report, the expressway was used by 200,645,817 cars in the 2022 fiscal year, with an average of 579,901 cars per day.<ref>{{Cite web |title=รายงานสถิติปริมาณจราจร รายได้ค่าผ่านทางพิเศษ และอุบัติเหตุบนทางพิเศษ ปีงบประมาณ 2565 |url=https://www.exat.co.th/statistics/%E0%B8%A3%E0%B8%B2%E0%B8%A2%E0%B8%87%E0%B8%B2%E0%B8%99%E0%B8%AA%E0%B8%96%E0%B8%B4%E0%B8%95%E0%B8%B4%E0%B8%9B%E0%B8%A3%E0%B8%B4%E0%B8%A1%E0%B8%B2%E0%B8%93%E0%B8%88%E0%B8%A3%E0%B8%B2%E0%B8%88%E0%B8%A3-5/}}</ref>
