The exit numbers correspond with the mileposts so some numbers may be skipped if the exits are further apart from one to the next. This section is multi-lane 3 to 8 in both directions and is busy with traffic at nearly all times of the day. If at all possible avoid driving at peak commuter times. Some drivers may be tempted to take Interstate as an alternate route, but check traffic conditions before doing so as it is often even worse for traffic congestion.
The road climbs out of the San Fernando Valley, which although multi-lane will have slow-moving traffic before entering the Santa Clarita Valley. Oddly, at one point the north and south bound carriageways cross and run for a number of miles separate from one another.
Most of this section is two-lane carriageway in both directions, running straight with only small rises though sparsely populated areas. Most of the route here is uninteresting, though in some places small detours reveal points of interest. Interstate travelers in Oregon should be aware that it is illegal to pump your own gas in the counties through which I-5 passes although Oregon law changed in to allow stations in certain counties to offer self-service, I-5 doesn't pass through any of them.
When you arrive at a filling station wait for an attendant to come to your car rather than attempting to get out and fill up your car on your own. Some of the highway rest stops in Washington are also staffed by volunteers from different local religious and fraternal organizations such as the Lions Club or Elk's Club to offer free coffee, tea, water and cookies to travelers.
Some even offer home baked goods such as brownies too. A donation of any amount is appreciated in the can provided on the counter. Rest stops in Washington state do not have exit numbers but rather marked with a blue sign rather than the green sign. North of Olympia the interstate enters the large conurbation of cities in Thurston, Pierce, King and Snohomish counties. This section is multi-lane 3 to 5 in both directions and is busy with traffic at nearly all times of the day.
Some drivers may be tempted to take Interstate through Bellevue as an alternate route, but check traffic conditions before doing so as it is often even worse for traffic congestion than Interstate 5. Exits into local side streets may of changed so follow signs closely and prepare for heavy traffic of less than 50 mph going through this area. On southbound I-5, one of four lanes is shift to what is normally the northbound inner shoulder between approximately Lake Hughes Road and Hasley Canyon Road.
A: No. The bypass lane is protected by k-rails and the existing center median. Once drivers enter the bypass lane, they will not be able to exit until the lane shifts back to the original lane pattern. In other areas of the roadway rehabilitation project, a 55 mph speed limit is in effect. A: No, this is a roadway rehabilitation project. Construction of carpool lanes also called HOV or High Occupancy Vehicle lanes on this segment of I-5 is anticipated under a separate project following completion of this project.
Construction is anticipated to begin in Background This portion of I-5 has pavement that is more than 50 years old and is no longer adequate for the existing and future traffic loads. Benefits Once completed, the new surface will provide a smoother, safer drive for motorists and will reduce time required for future maintenance, which will minimize future lane closures and delays for drivers.
Project Elements To assure a smoother ride, concrete paving will be continuously upgraded in the outside lanes 3 and 4 lanes. New Temporary lanes Starting in mid-December , new temporary lanes were added on two portions of northbound and southbound I Northbound Bypass Lanes On northbound I-5, one of four lanes is shifted to what is normally the inner southbound shoulder near Magic Mountain Parkway, and then returns to the northbound side north of Hasley Canyon Road.
The work area is protected by K-rails, and the split lanes will run for less than a mile. Schedule Construction phase begins Summer Construction phase ends Summer Project Area The project is under construction along Q: What are the times of construction activities? Q: Will freeway lanes be closed during construction?
I-5 was generally six lanes wide. Construction expanded the freeway northwest from Buena Park to Commerce. Construction continued on Segment A through December For more, please see the official web page. One of the biggest congestion points along Interstate 5 is at its junction with I, U.
This maze of interchanges, ramps and other maneuvers remains largely unchanged since its original construction, and so it is overwhelmed by traffic every day. Through traffic on I-5 is squeezed into two lanes at one point as well as merged with traffic from the busiest freeway in Southern California, Interstate 10 Santa Monica Freeway. From here, Interstate 5 generally follows old U. Leaving the Los Angeles Basin, Interstate 5 regains its full freeway configuration of eight to ten lanes, but the evening commute generally hits at the north end of San Fernando Valley.
The interchange between I-5, I and SR 14 is a choke point, even with the truck bypass. Beyond San Fernando Valley, Interstate 5 ascends to one of the highest points along its course along the western coast. Crossing the Tehachapi Mountains at Tejon Pass elevation 4, feet as well as the infamous San Andreas fault, I-5 transitions from an urban to a rural freeway for the first time. In order to make the grade manageable for trucks, the northbound lanes of I-5 just north of Castaic switches sides with the southbound lanes.
The result is several miles in which northbound Interstate 5 is on the left side of the freeway rather than the right side.
This kind of configuration is uncommon; Interstate 8 east of Yuma, Arizona has a similar inversion of its east and westbound lanes. Descending into the massive Central Valley via the Grapevine, Interstate 5 immediately splits into two routes: I-5 follows the Westside Highway, avoiding all major population centers between the Grapevine and Tracy. SR 99 follows the old U. Fresno holds the dubious distinction as the largest city in the country not served by an Interstate highway.
Nevertheless, Fresno still has its old standby, SR Most traffic destined for the Bay Area and points northward prefer to take Interstate 5, which is shorter and avoids urban traffic.
The next several hundred miles can be peaceful or stressful depending on the day of the week and time of year. During holiday weekends, Interstate 5 can be a parking lot filled with travelers eager to reach relatives and friends in Northern or Southern California.
At other times, I-5 is as free-flowing as any rural freeway. As this kind of usage increases, traffic delays become problematic in the Central Valley, even if the nearest city is many miles away.
Once at Interstate , travelers en route to the San Francisco Bay Area may exit west to their destination. I-5 remains in the Central Valley, closely following the California Aqueduct and Path 22, the flagship transmission power lines that follow the freeway through much of the state.
Whenever Southern California needs power from Northern California, these power lines carry that extra power needed to satisfy their needs. The power lines also work in reverse, thus ensuring that neither part of the state is without power for a long period of time. By the time Interstate 5 reaches Sacramento, it has expanded to eight to ten lanes. Passing under Business Loop I, I-5 is well below grade … so low that the bottom of the nearby Sacramento River is higher than the level of the freeway as it passes by Old Town Sacramento.
Occasionally, with significant amounts of rain and other variables, this section of Interstate 5 may flood. However, there are plans to change this. Some Sacramento leaders want to see their access to the river restored, and part of that would require removing Interstate 5 from between downtown Sacramento and Old Town Sacramento. This ambitious plan faces many hurdles, including major cost and environmental concerns, and nothing has been finalized. Interstate 5 leaves Sacramento almost as quickly as it arrived.
Most of the towns passed by Interstate 5 are small, but they have seen growth through the addition of fast food restaurants, gas stations and motels. Behind the veneer of these services, old towns with a great deal of history and farming tradition — such as Williams, Arbuckle, Willows, and Orland — await. I-5 leaves the Central Valley, and glimpses of towering Mount Shasta become common.
Changing from the great valley to mountain scenery, I-5 cuts towering mountains as it winds its way northward along old U. This terrain remains similar as Interstate 5 passes through northern California and enters southern Oregon. By the time it reaches Eugene, the freeway has entered the narrow Willamette Valley, and it approaches Portland.
Both Portland and Seattle have several concerns with Interstate 5.
