Los Angeles Port Opens $139m SR 47 Interchange, But Bridge Closure Looms

The Port of Los Angeles has completed a US$139 million reconfiguration of the SR 47 interchange, separating truck traffic from passenger vehicles across one of the port's busiest transportation corridors and re-routing key connections between the Vincent Thomas Bridge, I-110, Harbor Boulevard and Front Street.

The ribbon-cutting, held at the waterfront, also marked the delivery of more than US$18 million in adjacent community beautification works. For drayage operators and terminal trucking fleets serving the San Pedro Bay complex, the more consequential number is what comes next: the Vincent Thomas Bridge will close entirely from November 7 for Caltrans' bridge deck replacement project, and the new Harbor Boulevard on-ramp will stay shut in coordination with that work.

What changes on the ground?

The core engineering move relocates the southbound SR 47 off-ramp to Harbor Boulevard from the south side of the Vincent Thomas Bridge to its north side. According to the port, that improves traffic connections to San Pedro and the surrounding waterfront while smoothing cargo and motorist movement through the corridor.

The package of works includes:

• Reconfigured freeway ramps feeding the interchange;
• New turning and through lanes on Harbor Boulevard;
• A dedicated lane giving trucks direct access to the West Basin Container Terminal.

That last item matters most for container flows. The West Basin terminal is one of the port's principal box facilities, and a dedicated access lane removes a segment of street running shared with commuter traffic — a small but real gain in gate predictability for carriers and BCOs moving cargo through San Pedro Bay.

Who paid for it?

The port secured more than US$73 million in grant funding for the interchange — roughly half the project's cost — from LA Metro, Caltrans, the South Bay Cities Council of Governments and the US Department of Transportation. The balance came from port resources. The grant share underlines how much of America's largest container gateway depends on outside transport agencies to fund landside capacity, even as the port itself books record cargo volumes.

What about the $18m in street-level works?

Three beautification projects totalling more than US$18 million were completed alongside the interchange. The largest, the US$10.5 million Front Street Beautification Project, delivers a 22-foot-wide landscaped area and multi-use path along the north side of Front Street, which runs adjacent to the West Basin Container Terminal — meaning truck routes and a public promenade now share a deliberately designed boundary.

The remaining two are smaller. The approximately US$1 million Front Street West Project improved the west side of Front Street at Pacific Avenue. The US$7 million North Gaffey Street Beautification Phase II added landscaping and a multi-use path along the east side of Gaffey Street between Gatun and Channel Streets, plus improvements to the Caltrans Park and Ride site.

Is the congestion problem solved?

Not yet, and the port has not claimed it is. The completed interchange removes one specific friction point — mixed truck and passenger movements at the SR 47 connection — but the November 7 Vincent Thomas Bridge closure will test whether the new ramp geometry can absorb diverted traffic. Caltrans has not published an end date for the deck replacement in the material released with the ceremony, and the port's own statement acknowledges the Harbor Boulevard on-ramp will remain closed until that separate project is finished.

For shippers routing containers through Los Angeles this quarter, the practical read is mixed: better terminal access on one side of the ledger, a full bridge closure on the other. Carriers and drayage firms planning November and December pickup schedules should assume corridor capacity remains constrained until Caltrans signals the deck replacement's timeline, with the new interchange's benefits fully measurable only after the bridge reopens.
