The UPS driver was stuck. Again. I watched from my Accord as the brown delivery truck tried to navigate the right turn from southbound Morena Boulevard onto eastbound Mission Bay Drive, its rear wheels tracking dangerously close to the curb while oncoming traffic stacked up behind a line of cars waiting for the 40-foot truck to complete its awkward dance. This scene plays out daily on Morena Boulevard, where the combination of narrow lanes, tight curves, and heavy truck traffic creates one of San Diego's most predictable traffic headaches.
The Geometry Problem
Morena Boulevard wasn't designed for today's truck traffic. Built in the 1960s when delivery vehicles were smaller and online shopping didn't exist, the four-lane road features 11-foot lanes — barely adequate for a standard passenger car, let alone a 53-foot semi trying to navigate the curves between Clairemont Drive and Mission Bay Drive.
The worst section runs from Linda Vista Road south to the Mission Bay Drive intersection. Here, the roadway curves gently but consistently, with no shoulder and concrete barriers on both sides in several spots. A fully loaded delivery truck needs every inch of its lane plus some of the adjacent one to stay on the pavement. I've seen countless trucks drift into oncoming traffic on these curves, forcing cars to brake hard or swerve into bike lanes.
The Mission Bay Drive intersection is where geometry becomes genuinely dangerous. The right turn requires trucks to swing wide into the left lane, while the left turn forces them to cut the corner or risk their trailer tracking over the sidewalk. During SeaWorld's busy season, when tourist traffic backs up in all directions, these turning movements can block the entire intersection for multiple light cycles.
Daily Delivery Disasters
Amazon, FedEx, UPS, and local delivery companies run hundreds of trucks down Morena Boulevard daily, heading to businesses in Mission Bay, SeaWorld, and the hotels along Mission Bay Drive. Most drivers figure out the challenges after a few runs, but the constant stream of rental trucks, moving vans, and out-of-state commercial vehicles keeps the problems fresh.
I regularly see delivery trucks stopped in the right lane with their hazards on, drivers outside assessing whether they can make the upcoming turn without hitting something. The curve near Napa Street is particularly notorious — trucks approaching from the north can't see the severity of the bend until they're committed, leading to last-second lane changes that infuriate following traffic.
Food trucks face their own special hell on Morena. These vehicles combine the worst aspects of truck size with the handling characteristics of a top-heavy van. I watched a taco truck get completely sideways trying to turn left from Morena onto Clairemont Drive during lunch rush, blocking three lanes of traffic while the driver made a seven-point turn to get straightened out.
When Things Go Wrong
Breakdowns on Morena Boulevard create instant gridlock. The narrow lanes mean a disabled truck essentially closes half the road, forcing all traffic into a single lane while emergency vehicles try to respond. Last month, a delivery truck broke down just south of Balboa Avenue during morning rush hour, creating backups that reached I-5.
Commercial vehicle operators dealing with breakdowns on this stretch need specialized help. Highway Heroes Towing handles a lot of these calls in the Clairemont area and knows how to navigate the tight spaces and traffic complications that make Morena Boulevard recoveries particularly tricky.
The worst incidents happen when trucks attempt U-turns. Morena Boulevard has several median breaks that look inviting to drivers who realize they're heading the wrong direction, but the turning radius required exceeds what the road geometry allows. I've seen trucks high-centered on medians, trailers jackknifed across multiple lanes, and one memorable incident where a moving truck got so twisted around that it took three tow trucks and a traffic control team two hours to clear the mess.
The GPS Problem
Modern GPS systems bear significant responsibility for Morena Boulevard's truck troubles. Mapping algorithms prioritize shortest distance and don't account for vehicle size or road geometry. A trucker following GPS directions from I-5 to Mission Bay gets routed down the Morena Boulevard exit because it's technically 0.3 miles shorter than taking Sea World Drive.
Local delivery drivers learn to ignore their GPS and take Sea World Drive instead — it's wider, has better sight lines, and connects to Mission Bay Drive with a much more forgiving intersection. But out-of-town drivers, rental truck operators, and anyone following their phone's directions ends up on Morena Boulevard, discovering too late that shortest doesn't mean best.
The city has discussed adding truck restriction signs, but the businesses along Morena Boulevard depend on delivery access. The result is a compromise that satisfies no one: trucks are technically allowed but practically challenged every time they attempt the route.
The Real Solution
Smart truck drivers avoid Morena Boulevard entirely. The Sea World Drive route adds maybe two minutes to a trip but eliminates the stress, delays, and potential damage that comes with navigating Morena's tight quarters. For drivers heading to destinations east of Mission Bay, taking I-5 to I-8 and approaching from the south often proves faster despite the longer distance.
Until the city widens Morena Boulevard or restricts truck traffic — both expensive and politically complicated solutions — the daily dance of oversized vehicles on undersized infrastructure will continue. Local drivers know to give trucks extra room and patience on this stretch. Out-of-town truckers learn the hard way that sometimes the shortest route is the longest trip of your day.
