Catching up on construction, Part 2


Welcome to the second part of the northside taxiway construction story. We pick up in February, 2024. Once we made it out of the 2023 holiday season, the project expanded to include work on rebuilding Taxiway E with the intersections for the western exits (V and W). This stage of the project required the closure of the affected portion of Taxiway E, seen in the following photos:

Not really mentioned so far has been the opening of the extended portion of Taxiway D, which now runs all the way west to Taxiway AA. The fresh concrete visible in the second and third photos is the new Taxiway D extension. This gives us another parallel taxiway on the north side all the way to the west end of the airport. Therefore, even with the Taxiway E closure, it is still possible for aircraft to arrive on the 24s and taxi to their gates at Terminals 1, 2, and 3 -- with some exceptions. During the Taxiway E closure, there are restrictions on the size of aircraft that may use the new portion of Taxiway D to protect wingtips and the construction site. As such, B767s and smaller aircraft may use taxiway D adjacent to the construction zone; larger aircraft such as the B747 in the third photo have to taxi over to the south side to get around the restriction.

By the end of February, the Runway 24R/06L phase of the project was completed and the runway reopened. The new taxiways now needed to be continued on across Runway 24L/06R and tied into Taxiway E. In March, Runway 24L/06R closed for both the taxiway construction and runway centerline rehabilitation. The red on this diagram illustrates what was closed at this point:

With RY24L closed, we're now using RY24R for arrivals and departures

At the same time, Taxiway U isn't quite so far along

The RY24L centerline rehabilitation project started with the removal of the existing concrete with a really large jackhammer. About to touch down on RY24R is an Air Premia B787-9 Dreamliner arriving from Seoul, South Korea

The next three photos show the progress on Taxiway S over a week's time in early April:

This is how things looked by the end of April:

Catching up on construction, Part 1

Since late last summer, there's been some portion of the north runway complex closed for construction. The opening graphic, courtesy of Los Angeles World Airports (LAWA), shows the scope of the project. There will be four new runway exits, while the existing centerfield exits will be decommissioned. As part of this project, all of the runway entrances/exits will be renamed. The work began with the closure of Runway 24R/06L (the outboard runway) as well as some partial closures of Taxiway E. While the runway was closed for construction of the northern portion of the taxiways, LAWA also took the opportunity to replace some of the runway centerline. The following four photos show early stages of the work in September, 2023:
Taxiway E closed for construction of the tie-in for future Taxiway U. This is due north of the north end of the TBIT

Taken about the same time, progress on future Taxiway S

By October, we see the first concrete of Taxiway S

Looking over the top of Terminal 3, we can see the beginnings of Taxiway U

Early December progress on Taxiway U

Here we see both Taxiways U and S in January, 2024

In all of these photos, Runway 24R/06L is closed. This means that RY24L/06R, the inboard runway, is being utilized for both arriving and departing aircraft. For many airports it's everyday practice to use one runway for takeoffs and landings, but LAX typically lands on the outboard runways while departing from the inboards. We do this for for both safety and volume, so when one runway is having to perform double duty we generally will send more departures than usual to the other side of the airport. This post gets us through the middle of January of this year; future posts will continue the saga.
