Once completed, it will connect the Manila–Cavite Expressway in Kawit to the South Luzon Expressway in Biñan and is expected to ease the traffic congestion in the Cavite–Laguna area, particularly along the Aguinaldo Highway, Governor's Drive, and the Santa Rosa–Tagaytay Road. Route description 

CALAX begins as the Mamplasan Rotunda, a roundabout intersecting with South Luzon Expressway's Greenfield City-Unilab (Mamplasan) Exit, LIIP Avenue, and Greenfield Parkway in Biñan. It continues west then making a reverse curve to the southwest through the future Greenfield City Biñan development. It enters the Laguna Boulevard right of way near the boulevard's intersection with Greenfield Parkway. It approaches the first toll plaza near the Verdana Homes gated community, and continues southwest, passing through a mix of developed and undeveloped areas at barangays Loma, Timbao and Malamig, then turning south into barangay Biñan, where it passes near Laguna Technopark, De La Salle University – Laguna Campus and several gated communities; access for them is provided by service roads. The expressway partially runs above grade, utilizing underpass bridges, mechanically stabilized earth (MSE) walls and a viaduct at this section to pass above major intersections and accesses. Entering Santa Rosa, CALAX descends into grade level to cross the Silang–Santa Rosa River and clear a power line, then gently curves to the southwest to follow the Nuvali Boulevard right of way, where the expressway ascends above grade again to pass over South Boulevard, served by the Laguna Boulevard Exit. Past the exit, it leaves the Nuvali Boulevard right of way and crosses the Silang–Santa Rosa River once again, this time the Cavite–Laguna provincial boundary into Silang. It makes another reverse curve through cornfields to the Santa Rosa–Tagaytay Exit, a trumpet interchange which leads to Santa Rosa–Tagaytay Road. The expressway continues southwest and makes a few turns before traversing a bridge and enters a cut section, passing near the Ayala Westgrove Heights. It turns northwest and passes under Tibig Road before ending at Silang East Exit, a diamond interchange which leads to Tibig-Kaong Road. A future road will be built west of the Silang East interchange that will connect to the Cavite segment of the expressway. History

The groundbreaking ceremony for the Cavite segment was eventually held on March 27, 2019. Meanwhile, the Department of Public Works and Highways, then headed by Secretary Mark Villar, expected the Laguna segment to be opened by October 2019. The Laguna segment became partially operational while the Cavite segment is still undergoing construction. Both segments were expected to be fully operational and completed by 2022, but was delayed to 2023 due to the COVID-19 pandemic and again to 2024 due to construction delays.

The first  of the expressway has been made accessible on October 30, 2019, in time for All Saints' Day and All Souls' Day. The entry and exit points at Mamplasan Interchange in Biñan, Laguna and Santa Rosa–Tagaytay Road were opened to serve an estimated 10,000 cars.

The expressway was closed from January 28 to 31 and February 4 to 7, 2020 at 1:00 AM to 4:00 AM (PST) to give way for construction and clearing operations due to ashfalls brought by the 2020 Taal Volcano eruption. On August 18, 2020, the Laguna Technopark and Laguna Boulevard Exits in Biñan and Santa Rosa, respectively, were opened to the public. On August 24, 2021, the  section leading to the Silang East interchange in Silang, Cavite was opened to the public. However, this segment was supposed to be operational back in June 2021.
