The Gov. William Preston Lane Jr. Memorial Bridge is a major dual-span bridge in the U.S. state of Maryland. Spanning the Chesapeake Bay, it connects the state's rural Eastern Shore region with its urban and suburban Western Shore, running between Stevensville and Sandy Point State Park near the capital city of Annapolis. The original span, opened in 1952 and with a length of 4 miles (6.4 km), was the world's longest continuous over-water steel structure. The parallel span was added in 1973. The bridge is named for William Preston Lane Jr., who as the 52nd Governor of Maryland launched its construction in the late 1940s after decades of political indecision and public controversy.

<span class="mw-page-title-main">Reversible lane</span> Lane in which traffic may travel in either direction

A reversible lane is a managed lane in which traffic may travel in either direction, depending on certain conditions. Typically, it is meant to improve traffic flow during rush hours, by having overhead traffic lights and lighted street signs notifying drivers which lanes are open or closed to driving or turning.

<span class="mw-page-title-main">Arterial road</span> High-capacity urban road

An arterial road or arterial thoroughfare is a high-capacity urban road that sits below freeways/motorways on the road hierarchy in terms of traffic flow and speed. The primary function of an arterial road is to deliver traffic from collector roads to freeways or expressways, and between urban centres at the highest level of service possible. Therefore, many arteries are limited-access roads, or feature restrictions on private access. Because of their relatively high accessibility, many major roads face large amounts of land use and urban development, making them significant urban places.

<span class="mw-page-title-main">Bus lane</span> Road lane intended for buses and other transits only

A bus lane or bus-only lane is a lane restricted to buses, generally to speed up public transport that would be otherwise held up by traffic congestion. The related term busway describes a roadway completely dedicated for use by buses, whilst bus gate describes a short bus lane often used as a short cut for public transport. Bus lanes are a key component of a high-quality bus rapid transit (BRT) network, improving bus travel speeds and reliability by reducing delay caused by other traffic.

<span class="mw-page-title-main">Operation Stack</span> Contingency plan for traffic congestion in Kent

Operation Stack was a procedure used by Kent Police and the Port of Dover in England to park lorries on the M20 motorway in Kent when services across the English Channel, such as those through the Channel Tunnel or from the Port of Dover, are disrupted, for example by bad weather, industrial action, fire, or derailments in the tunnel. Since 2019, it has been superseded by the Operation Brock contraflow system.

In transport engineering nomenclature, a counterflow lane or contraflow lane is a lane in which traffic flows in the opposite direction of the surrounding lanes.

Contraflow lane reversal is the altering of the normal flow of traffic, typically on a controlled-access highway, to either aid in an emergency evacuation or, as part of routine maintenance activities, to facilitate widening or reconstruction of one of the highway's carriageways.

<span class="mw-page-title-main">Barrier transfer machine</span> Heavy vehicle used to transfer concrete lane dividers during rush hours

A barrier transfer machine, also known as zipper machine or road zipper, is a type of heavy vehicle that is used to transfer concrete lane dividers, such as Jersey barriers, in order to relieve traffic congestion during rush hours. Many other cities use them temporarily during construction work. The lanes created by the machine are sometimes referred to as "zipper lanes".

Counter-flow refers to the movement of culture that runs counter to the traditional dominant-to-dominated cultural adaptation patterns. In a contraflow situation, cultural elements brought into a society by immigrants become accepted and popular among the society at large. Examples include the world-wide popularity of telenovelas, anime and K-Pop.

<span class="mw-page-title-main">Managed lane</span>

A managed lane is a type of highway lane that is operated with a management scheme, such as lane use restrictions or variable tolling, to optimize traffic flow, vehicle throughput, or both. Definitions and goals vary among transport agencies, but managed lanes are generally implemented to achieve an improved operational condition on a highway, such as improving traffic speed and throughput, reducing air pollution, and improving safety. Types of managed lanes include high-occupancy vehicle (HOV) lanes, high-occupancy toll lanes, express toll lanes, reversible lanes, and bus lanes. Most managed lane facilities are located in the United States and Canada, although HOV and bus lanes can be found in many other countries; outside of the US and Canada, many countries use active traffic management that manage all lanes of a highway.

<span class="mw-page-title-main">Road signs in Georgia</span>

Road signs in Georgia are similar to the road sign system of other post-Soviet states that ensure that transport vehicles move safely and orderly, as well as to inform the participants of traffic built-in graphic icons. However, some road signs look a bit different from Soviet ones and closer to the European ones. These icons are governed by the Vienna Convention on Road Traffic and Vienna Convention on Road Signs and Signals.
