Denver is one of the largest and the most populous city of US state of Colorado. In addition to that it is home to many markets, businesses, offices etc and it has many other counties in it. Thus an efficient and well maintained transportation system is needed in the city to ensure that the people can move about the city freely, without facing any kind of problem or anything. The transpiration system in Denver consists of City streets, Freeways and highways, Mass transportation, airports, bicycle tracks etc.

As far as the city streets are concerned most of the Denver is connected via straightforward street grid. While the blocks located on these streets are numbered in hundreds, while the median streets are numbered ‘00’, this is Broadway. The major and the largest artery is the Colfax Avenue, which runs in the East – West artery through Denver having 15 blocks north of median. Then the Avenues south of Ellsworth are named while on the north they are numbered.

Hence, both the numbers and names are used to name a street. Then along with that there is an old downtown grid system too, designed by Henry Brown. This system was designed to in such a way that it runs parallel to the both Cherry Creek and South Platte River. The total street system of the city is complex and one may get confused where the two grids meet up, however there are adequate sign boards that one can read to take the correct path one wanted to choose. Many of these streets also have bicycle lanes for those who like to pedal more than driving or using public transport.

Denver is mainly served by the interstate freeways I-25 and I-70. I-25 runs from Mexico to Wyoming, I-225 runs from Aurora to southeastern corner of Denver. I-70 runs from Utah to Maryland. I-76 braches off from the I-70 just west of city Arvada, and it runs to I-80. Then there is US-6 and US 36. US-6 links the downtown Denver to Golden and Lakewood and continues as far as Massachusetts. US 36 links Denver to Boulder and Rocky Mountain National Park and runs into Ohio after it has crossed four other states. In addition to these freeways there are two toll highways that run through the city. As for the Mass transportation, it is managed by the Regional Transportation Department. It operates more than 1000 buses, five light rail lines the C, G, E, F, and H with the total of 34.9 miles. Then there is also national passenger rail system, providing services to Denver.

Denver International Airport or DIA serves as a primary airport for the large region surrounding the city. It is located to 18.6 miles east –northeast of Colorado State Capital. It is the 10th busiest airport in the world and ranks fourth in US for the number of passengers that travel through the gates of this airport. The airport is the largest in the US to accommodate a number of flights that come daily simultaneously. There were some other airports too in the city however they were all closed only the DIA remained in the end.
