MARYLAND MY MARYLAND MARYLAND BRIDGES THE CHESAPEAKE BAY BRIDGE

Bridge (Please watch this video)


Anyone from Maryland has been on this bridge. Especially if heading to the Eastern Shore. Many of us have probably sat in traffic on this bridge in the summer time.
The Chesapeake Bay Bridge (known locally as the "Bay 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 the urban Western Shore. The original span, opened in 1952 and with a length of 4.3 miles (6.9 km), was the world's longest continuous over-water steel structure. The parallel span was added in 1973. The bridge is officially named the Gov. William Preston Lane Jr. Memorial Bridge after William Preston Lane Jr. who, as the 52nd Governor of Maryland, initiated its construction in the late 1940s finally after decades of political indecision and public controversy.
The bridge is part of U.S. Route 50 (US 50) and US 301, and serves as a vital link in both routes. As part of cross-country US 50, it connects the Baltimore-Washington Metropolitan Area with Ocean City, Maryland, Rehoboth Beach, Delaware, and other coastal tourist resort destinations. As part of US 301, it serves as part of an alternative route for Interstate 95 travelers, between northern Delaware and the Washington, D.C., area. Because of this linkage, the bridge is busy and has become known as a point of traffic congestion, particularly during peak hours and summer months.
The bridge's role in transportation was filled by ferries prior to the first span's construction. An annual 10K run across the bridge has been organized on-and-off since 1975. The bridge's economic impact on the areas it connects has been significant, with both Queen Anne's County and Ocean City expanding significantly since the bridge's construction. Future expansion of the bridge has been discussed since 2004, with a task force being formed to investigate the possibility of building a third span.

History
Proposals and ferries
It is possible that studies may have been conducted as early as the 1880s into the possibility of a bridge across the Chesapeake Bay. However, the first known proposal came about in 1907 and called for a crossing between Baltimore and Tolchester Beach. In 1927, local businesspeople were authorized to finance the construction of a Baltimore to Tolchester Beach crossing. Plans for the new bridge were made, but construction was canceled following the Wall Street Crash of 1929 with the collapse of the American economy and resulting Great Depression of the 1930s.
Ferries were used as the main mode of transportation across the bay from the colonial period until the completion of the 1952 bridge. The first service ran from Annapolis to Broad Creek on Kent Island, roughly where the bridge is today. In 1919, the Claiborne–Annapolis Ferry Company began running ferries between Annapolis and Claiborne, a community near St. Michaels.
In July 1930, the Claiborne–Annapolis Ferry Company added a new route, one running from Annapolis to Matapeake, a significantly shorter distance. The auto and passenger ferries were taken over by the State Roads Commission in 1941 (reorganized into today's State Highway Administration of the Maryland Department of Transportation in 1973). Two years later, the commission moved the western terminus of the old Annapolis–Matapeake ferry to Sandy Point (later adjacent to Sandy Point State Park), shortening the cross-bay trip.
Construction of 1952 span
A 1938 proposal by the Maryland General Assembly was the first to call for a bridge at the Sandy Point–Kent Island location. Although the legislation authorizing the new bridge passed, the involvement of the United States in World War II delayed the bridge's construction. In 1947, with the war over, the Assembly, under the leadership of Maryland Governor William Preston Lane Jr., (1892–1967), passed legislation directing the old State Roads Commission to begin construction. Ground was broken in January 1949, and after a ​3 1⁄2-year construction project, the bridge opened to traffic on July 30, 1952, as both the longest continuous over-water steel structure, and the third longest bridge in the world. Before the opening, a parade of vehicles made the first official crossing, led by then current Governor Theodore Roosevelt McKeldin, (1900–1974), and other state officials in a distinctive white Cadillac convertible flying huge American and Maryland flags. On November 9, 1967, the bridge was dedicated to Governor Lane, who had died earlier that year, and officially renamed the "William Preston Lane Jr. Memorial Bridge".

1973 expansion
In 1967, due to increasing traffic volume, the Maryland General Assembly authorized three possible new crossings, all suggested during the 1964 Chesapeake Bay crossing study. These included one further north near Baltimore, one in southern Maryland, and an additional span to be added to the existing bridge from Kent Island to Sandy Point; ultimately, the third option was chosen. Construction of the new parallel span began in 1969 to the north of the original bridge, and it was completed on June 28, 1973.

Notable incidents
Because of its height, the narrowness of the spans (there are no hard shoulders), the low guardrails, and the frequency of high winds, it is often cited as one of the scariest bridges in the United States. Several weather-related incidents have caused complete closures of the bridge.
The bridge has been closed four times due to extreme weather. The first time was September 18, 2003, during Hurricane Isabel and its high winds. On August 27, 2011, the bridge was closed to all traffic due to the impact of Hurricane Irene. Then-Governor Martin O'Malley ordered the bridge closed when sustained winds exceeded 55 miles per hour (89 km/h). On October 29, 2012, the bridge was closed due to the effects of Hurricane Sandy. On March 6, 2013, during the March 2013 nor'easter, high winds again caused the bridge to be closed.
On August 10, 2008, a tractor trailer involved in a head-on collision near the west end fell from the bridge; the driver died in the crash. The incident highlighted concern that the bridge may not be structurally safe, but the Maryland Transportation Authority (MDTA) discounted any structural or engineering problems with it. Inspections of the wall in the weeks following the accident revealed that there was deterioration in the form of corrosion of the steel reinforcements inside barriers; this prompted immediate repairs to the wall.

Specifications and operations
With shore-to-shore lengths of 4.33 and 4.35 miles (6.97 and 7.00 km), the two spans of the bridge form the longest fixed water crossing in Maryland. The bridge's western terminus is in Sandy Point State Park, located northeast of Annapolis in Anne Arundel County, and its eastern terminus is in Stevensville on Kent Island in Queen Anne's County. The two spans are relatively similar in height, with the older span at 354 feet (108 m) and the newer span at 379 feet (116 m).

Structural details
With the exception of the number of lanes on each (two on the original span and three on the newer span) and differences owing to the design standards for the periods in which they were built, the spans are structurally similar. Both were designed by J. E. Greiner Company, which later became a part of AECOM through the company's acquisition of URS Corporation. Each span features:

Two main spans over the bay's two shipping channels:

A 3,200-foot (975 m) suspension span over the western channel with a maximum clearance of 186 feet (56.7 m)—high enough to accommodate ocean-going vessels and tall ships

A through-truss cantilever span over the eastern channel

Deck truss and steel girder spans flanking the main spans

Concrete beam spans on the portions closest to the shores

A curve near the western terminus, which is required so that the main spans cross the bay's shipping channels at 90 degrees per United States Army Corps of Engineers requirements.

Traffic control.
Traffic patterns on the bridge's five lanes can be adjusted via its lane control system, which consists of overhead lane control signals on both spans and approaches.Typically, the two lanes on the south-most span are configured for vehicles traveling east on eastbound US 50/US 301, while the three lanes on the north-most span are configured for vehicles traveling west on westbound US 50/US 301; the spans are therefore referred to as the "eastbound span" and "westbound span", respectively. However, this pattern is adjusted during incidents or peak travel times: for instance, on the outset of weekends when there is a high volume of beach-bound traffic, one lane on the westbound span is configured for eastbound traffic.
In 2006, pink markers were placed along the eastbound span to mark out the suggested following distance, similar to systems used in Minnesota and Pennsylvania. The markers are a part of the MDTA's "Pace Your Space" campaign to prevent vehicle collisions and traffic congestion due to tailgating on the bridge.
In April 2013, changes were made to increase safety on the westbound span during two-way operations: signs, pavement markings, and rumble strips were modified, and a buffer zone between the left and center lanes was created. As a result, motorists can no longer switch between the left and center lanes, whether or not two-way operations are in effect. Two-way traffic may occur on the eastbound span during overnight roadwork or during emergency situations that close the westbound span, on which two-way traffic is more common. When the MDTA closes either span for overnight roadwork, it implements two-way traffic on the span that remains open. During eastbound span closure, two-way traffic operates on the westbound span with the center lane closed.
In January 2020, Governor Larry Hogan announced that the tollbooths on the eastbound side of bridge were being removed in preparation for all-electronic tolling on the Kent Island side of the eastbound bridge. The merged lanes tie directly into the two lanes on the eastbound bridge. The MDTA is replacing lane control signals on both bridges with those that have flashing strobe lights to indicate a lane closure or a lane with contraflow traffic, and is installing an automated gate system on the bridge to allow quicker implementation of two-way traffic on the bridge. The automated gate system will reduce traffic congestion when implementing two-way traffic.
The MDTA has used traffic cones and barrels to open and close crossovers, and to create tapers for the reversible lane. When two-way traffic is implemented, the MDTA momentarily stops traffic to reposition traffic cones and barrels to taper traffic into the reversible lane. MDTA Police then escort traffic across the bridge in the reversible lane. The MDTA will not implement two-way traffic in certain weather conditions, including excess precipitation and high winds. The MDTA may stop all traffic when the wind speed exceeds 55 mph. Two-way traffic on the bridge requires all associated signage and systems to be operational. The MDTA has to monitor two-way traffic operations on the bridge due to the length of the bridge and its lack of shoulders. The MDTA will stop two-way traffic if westbound delays pile up, at which point westbound traffic will be prioritized. Any time contraflow traffic is implemented on either of the bridges, the speed limit for the contraflow lane is reduced to 40 mph while the other lanes remain at 50 mph. MDTA Police will momentarily stop traffic for MDTA crews to reposition traffic cones and barrels to close off the left lane leading up to the bridge in the event of inclement weather during contraflow traffic.

Tolls and fees
Operated by the MDTA, the bridge has a one-way toll (eastbound) of $4.00 for two-axle vehicles; vehicles with a Maryland E-ZPass pay $2.50. Previously the bridge had a one-way (eastbound) toll of $6.00 for two-axle vehicles (raised from $4 on July 1, 2013); vehicles with E-ZPass that were enrolled in the Bay Bridge Commuter Plan paid $2.10 (raised from $1 on July 1, 2013). Tolls were collected in both directions until April 1989, when tolls were doubled and only collected in the Eastbound direction. All-electronic tolling began on May 12, 2020, with tolls payable through E-ZPass or Video Tolling, which uses automatic license plate recognition.
The MDTA previously provided transportation across the bridge for nervous drivers, but that role is now filled by private companies.

Impact
Since its construction, the bridge has made significant impacts on both sides of the bay; among them has been the growth of Eastern Shore communities. When the bridge opened in 1952, and again when the second span was added in 1973, the Eastern Shore was given easier access to Baltimore and Washington, causing areas in southern Queen Anne's County to develop as bedroom communities. This extension of the Baltimore–Washington suburbs has led Queen Anne's County to be listed as part of the Baltimore–Washington Metropolitan Area. The bridge has also given easier access to Ocean City from the Western Shore, which has caused Ocean City to grow from a small town to one that is said to become the second largest city in Maryland during the summer.
In 1948, the impending completion of the bridge gave rise to an extension of US 50 to Ocean City. The route was extended along the corridor of Maryland Route 404 (MD 404) and a large portion of US 213, cutting both of those routes back. During the 1950s, US 50 on the Western Shore was rerouted onto the long-proposed Annapolis–Washington Expressway (now known as the John Hanson Highway), which was built at the time in order to provide better access to the bridge. As the Eastern Shore, particularly Ocean City, grew, further upgrades and realignments of US 50 took place. This work included the aforementioned 1973 completion of the second Bay Bridge span, the extension of the US 50 freeway eastward to the US 50/US 301 split in Queenstown, and the construction of a freeway bypass around the north side of Salisbury in 2002. Additionally, the road has been upgraded and realigned over the years from its original two-lane configuration to a four-lane divided highway, with the last such section being in Vienna, bypassed in 1991. Previous plans to expand US 50's freeway portion and replace the aging Harry W. Kelley Memorial Bridge into Ocean City have been delayed.
The bridge is often the site of suicides by jumpers. As of 1995, more than 75 people had committed suicide during the bridge's 43-year existence.
