The new interchange among the four Los Angeles freeways, including the grade-constructed accesses, occupies by itself no less than eighty acres of downtown land, one-eighth of a square mile, an area about the size of Rockefeller Center in New York.

In some cases, renewal may result in urban sprawl and less congestion when areas of cities receive freeways and expressways.

Public outcry convinced Caltrans to install the standard post-and-metal-beam barrier the entire length of the freeway and also to change their regulations so that median barriers are now required on all high-volume freeways with medians of less than 75 feet ( 23 m ).

A 1999 FHWA study concluded that " a best guess " might be 20 % to 30 % reduction in single-vehicle run-off-road crashes on rural freeways, with less effective on urban freeways.

Because of its relatively short length, the Glendale Freeway is often less congested in comparison to other Los Angeles freeways.

The total cost of the proposed highway and rail system was less than the 1959 plan due to the elimination of controversial freeways.

Roads to the east and west are less well developed, as there are no freeways travelling in that direction.

Like all Western Australian freeways, the minimum allowed speed, where safe, is always less than the maximum speed limit.

Now because the NJDOT does not want to pay to fix the problem, the exit has been barricaded since the freeways extension was opened.

Thus, the freeway has the distinction of being one of the few Ontario-maintained freeways not numbered according to the 400-Series Highway network, even though it is busier and wider than many rural 400-series highways, because the freeway upgrade has put together only parts of existing routes.

Some roadway advocates note that because of underlying factors ( e. g. population and income growth ), traffic will grow anyway, whether or not freeways are expanded ( this being the argument mentioned previously in relation to traffic forecasts ).

This can occur because responding units must drive around freeways, lakes, or terrain obstructions in order to reach a zone.

There is no connector route to I-5 South because the angle between the two freeways is too acute.

The interchange is so complex because the intersecting freeways shift alignments and directions:

In some places there are large divided roads with few or no driveways that cannot be called freeways because they have occasional at-grade intersections with traffic lights that stop traffic ( expressways in California, dual carriageways in Britain ) or they are just too short ( superarterials in Nevada ).

However, the building of freeways and garages cannot continue forever.

Advocates of ramp meters claim that they break up platoons of vehicles entering freeways, ensuring that traffic can merge more easily.

Nonetheless, Ontario freeways do not receive a 400-series number unless they are designed to be complete controlled-access freeways for their whole length.

The system had a fair amount of controversy when it was announced that it would use FasTrak electronic toll tags to track vehicles as they traversed Bay Area freeways.

This routing required some major infrastructure work on US 22 west of Downtown Pittsburgh ( particularly at the US 22 / US 30 cloverleaf in Robinson Township ) and safety improvements to PA 60 ; though both were limited access freeways before the extension, they were not up to Interstate Highway standards in all areas.

The 110 km Sydney orbital consists of several motorways and freeways, they are listed below:

Melburnians in general are divided over the freeways ; supporters crying " progress and growth " and detractors lamenting for example, the destruction of habitats and the loss of peace and tranquillity along the freeway path and at the ends where the freeway traffic is spilled onto local roads, the increased reliance on private automobiles and the economic, social and environmental costs they bring, the inefficiency of road transport versus the efficiency of public transport.

Generally occurring on high capacity and high speed routes such as freeways, they are one of the deadliest forms of traffic accidents.

Due to the space efficiency of SPUIs relative to the volume of traffic they can handle, the interchange design is being used extensively in the reconstruction of existing freeways as well as constructing new freeways, particularly in dense urban environments.

In California, Caltrans currently has a policy that whenever cloverleaf interchanges between freeways and surface streets are being rebuilt to handle higher traffic loads, they are turned into parclo interchanges by removing some of the loop ramps ( or in rare cases bridges will be added between adjacent loop ramps — see cloverleaf interchange for details ).

However, as for cloverleaf interchanges between freeways, they are being unwound into partial stack interchanges or made safer with slip ramps as funds permit.

" Big government " positions they take include further construction of freeways, funding for embryonic stem cell research, an enhanced federal role in emergency preparedness for the Federal Emergency Management Agency ( FEMA ), increased federal law enforcement on the border.

In the United States, they are sometimes called Jersey freeways, due to their prevalence in the state of New Jersey, although they are not limited to that state.

The route interchanges with Interstate 805 ; however, one can only continue in the same direction that they were at this intersection, since this is the interchange of two north – south freeways, resulting in the overall shape of an " X.

Designation as a regional road also does not imply any particular size of road ; they range from gravel roads to multi-lane freeways.

The Freeway Killer was a nickname given by the media — and later police forces — to what they believed was a single serial killer claiming victims in California, USA, during the 1970s and often dumping the victims along the freeways.

The ramps would also likely be expensive due to the large amount of rock in the area, as is seen on both freeways where they cross the ridge immediately north of where they split.

Sorrento Valley is located between the I-5 and I-805 freeways just below where they merge and / or split.

I-70, US 63, and US 40 are the main freeways used for travel to and from Columbia.

Indonesia has some highways, some of them are National Routes ( 25, currently only in Java ), and some of them are freeways.

All the freeways are tolled ( toll road ).

Absent this feedback mechanism the delays become both unpredictable and rise sharply, a symptom also seen as freeways approach capacity ; metered onramps are the most effective solution there, just as TCP's self-regulation is the most effective solution when the traffic is packets instead of cars ).

Some freeways are called expressways, super-highways, or turnpikes, depending on local usage.

Systems of freeways and expressways are also built to connect distant and regional cities, notable systems include the Interstate highways, the Autobahnen and the Expressway Network of the People's Republic of China.

Metered freeways are also a solution for controlling rush hour traffic.

These features are typically present on highways built as motorways ( freeways ).

Interstate 5 and Oregon Route 217 are the main freeways in the city, with Oregon Route 99W and Oregon Route 210 serving as other major highways, with rail service provided by the TriMet operated Westside Express Service.

Populations living near airports or freeways are exposed to levels of noise typically in the 65 to 75 dB ( A ) range.

Israel's road network spans 18, 096 km of roads, of which 230 km are classified as freeways.

Ramp meters are claimed to reduce congestion ( increase speed and volume ) on freeways by reducing demand and by breaking up platoons of cars.

There are no freeways in the town of Mashpee.

* There are no freeways within town ; Route 128 provides the nearest access in Manchester-by-the-Sea.

Other freeways are the A5, from Hoofddorp to Haarlem ( officially ends in Badhoevedorp ), A9 from Alkmaar to Diemen and the A44, from Nieuw-Vennep to Wassenaar.

There are currently no freeways that pass through Laughlin.

* US 64 and U. S. 1 are both freeways in the Apex area.

A large portion of old, two-lane US 12 was replaced by Interstate 82 and Interstate 182 in the 1980s, between Yakima and the Tri-Cities, though the freeways are still cosigned with the US 12 designation.

These are not freeways, having a slow 25-mile per hour speed limit, pedestrian crossings, and stop signs.

* Sites with extremely high traffic, or roads where pedestrians are not allowed ( freeways or motorways ) may instead be crossed via pedestrian bridges or tunnels.

Disyllabic names of railway lines, freeways, and provinces are often formed by taking one character from each of the two locales ' names.

These freeways are examples of the clash of urban community versus suburban market interests.

Advocates of highway development and suburban participation in urban government theorize that cities which protect themselves from the suburbs, forcing them to become self-sufficient small towns, cutting off the freeways, forcing commuters into subways, etc., are committing suicide by forcing business out into the suburbs.
