The Private Investment Promotion Agency (PROINVERSIÓN) has reported that in the Peripheral Ring Road project, the concessionaire will build and/or improve approximately 30 km of alternate or lateral roads in Peru.

Alternate or side roads will undergo construction and/or enhancements in all urban areas along the 34.8-km contemporary highway route, excluding segments with no consolidated urban development and tunnel zones. The enhancements to the alternative routes are planned for Section 1 of the Peripheral Ring Road, spanning from the 200-mile Oval (Callao) to the Pan-American Highway North (Ovalo Naranjal). Additionally, improvements will occur in Section 3, which extends from Av. Las Gaviotas (Ate Vitarte) to Av. Circunvalación (San Luis). In Section 2, covering the stretch from Panamericana Norte (Ovalo Naranjal) to Av. Ramiro Prialé (Lurigancho Chosica), the concessionaire will be responsible for the complete construction of alternate roads. This initiative aims to facilitate the movement of a Bus Rapid Transit (BRT) Corridor, accommodating a significant number of passengers daily and connecting them with existing mass transportation systems in the region, including Metro lines, Metropolitano, and a forthcoming cable car project. Consequently, the Peripheral Ring Road not only supports the construction and enhancement of auxiliary roads and improves connectivity to trade logistics centers but also ensures environmental compatibility by incorporating green spaces along the 35 km of the modern road. Ultimately, this project will contribute to a 13% reduction in Peru's transportation infrastructure gap.

The project costs around US$3.4 billion. The main expressway features three lanes in each direction with toll-free auxiliary roads enhancing urban connectivity. The design speed is 80 km/h (except for a specific curve at 70 km/h). Notable construction elements include two double tunnels (approx. 2 km each) in Section 2, along with eleven viaducts, sixteen underpasses, and eighteen overpasses.
