Lat Ya Road (Thai: ถนนลาดหญ้า, RTGS: Thanon Lat Ya, pronounced [tʰā.nǒn lâːt jâː]) is one of the major roads in Khlong San District, on the Thonburi side (the west bank of the Chao Phraya River) of Bangkok. It was constructed in 1929 during the reign of King Rama VII as the fourth of eleven roads developed on the Thonburi side, in anticipation of the expansion of land transportation in the future. In 1932, marking the 150th anniversary of Rattanakosin (Bangkok), the Memorial Bridge was built across the Chao Phraya River to connect the Phra Nakhon (Bangkok core) and Thonburi sides. The name "Lat Ya" is derived from the Battle of Lat Ya (present-day Lat Ya Subdistrict, Mueang Kanchanaburi District, Kanchanaburi Province), where Siamese forces led by Prince Maha Sura Singhanat achieved victory over the Burmese army. This battle was part of the Nine Armies' War (1785–86) during the reign of King Rama I in the early Rattanakosin period. The road was laid through land that had originally been orchards, such as longkong groves. At first, it was merely a gravel road surfaced with crushed stone, and the roadside utility poles were simple electric poles. At present, the road has six traffic lanes with a central median, a total width of 28 m (91.9 ft), and a length of 1,650 m (5,413.4 ft) It begins at Wongwian Yai, the site of the King Taksin the Great Monument, and runs northeast, passing the three-way Lat Ya Junction, where Itsaraphap Road and Tha Din Daeng Road begin, before continuing straight and terminating at Khlong San Junction, where it meets Charoen Nakhon Road and Somdet Chao Phraya Road, in front of Taksin Hospital and the Khlong San District Office. Lat Ya Road, particularly the stretch from Platform mall (formerly Robinson and Central Lat Ya) to Lat Ya Junction, is especially lively at night, lined with numerous street food vendors, notably chim chum eateries, many of which have been in operation for over 20–30 years. During the 1980s and 1990s, the area was also home to several suki restaurants, along with various dining spots and steakhouses. It was once the site of Thonburi Café, a large and well-known nightclub and restaurant in Bangkok during the heyday of such venues. In addition, around December 28 each year, the entire road is typically closed and turned into a pedestrian street for celebrations marking King Taksin the Great Day, with the festivities lasting about two to three days depending on the year.

Prajadhipok Road (Thai: ถนนประชาธิปก, RTGS: Thanon Prachathipok, pronounced [tʰā.nǒn prā.t͡ɕʰāː.tʰí.pòk]) is a road in Thon Buri District, Bangkok. It begins at Wongwian Yai and runs northeast, passing Ban Khaek Intersection, where it meets Itsaraphap Road. It continues past Wongwian Lek, crossing Khlong Somdet Chao Phraya just before reaching the roundabout, and passing in front of Suksanari School and the clock tower at Wongwian Lek. The road then splits into three routes. One branch veers slightly left, passes beneath the approach to the Memorial Bridge, curves toward Wat Prayurawongsawat, and loops under the bridge to connect with Phaya Mai Road, an area known for another Buddha amulet market in Bangkok apart from Tha Phrachan, on the Wongwian Lek side. The second branch continues straight across the Memorial Bridge toward the Pak Khlong Talat area in Wang Burapha Phirom Subdistrict, Phra Nakhon District. The third branch leads onto Phra Pok Klao Bridge, which runs parallel to the Memorial Bridge. At the end of the bridge, it splits again into two directions, one descending into the Phahurat area in Wang Burapha Phirom Subdistrict, Phra Nakhon District, and the other veering right toward the Chakkrawat area in Samphanthawong District. The road also serves as a boundary line. From its starting point at Wongwian Yai to Ban Khaek Intersection, the side leading toward the Memorial Bridge is within Hiran Ruchi Subdistrict, and beyond that point it becomes Wat Kanlaya Subdistrict. Both subdistricts belong to Thon Buri District, while the opposite side is entirely within Somdet Chao Phraya Subdistrict of Khlong San District. It was constructed in 1929 as the first road in a project to build 11 roads on the Thonburi side (the west bank of the Chao Phraya River), intended to support the future growth of land transportation. In 1932, marking the 150th anniversary of Rattanakosin (Bangkok), the government under King Prajadhipok (Rama VII) launched a megaproject to construct the Memorial Bridge, connecting Phra Nakhon (the main core of Bangkok) with Thonburi. After its completion, the road was named "Prajadhipok" in honor of the king. Since March 2024, Prajadhipok Road between Ban Khaek Intersection and the area in front of Suksanari School has experienced traffic congestion due to the construction of Saphan Phut Station (PP24), an underground station on the MRT Purple Line extension (Tao Poon–Rat Burana, Kanchanaphisek Ring Road). As a result, traffic flow in the area has had to be reconfigured.
