Merrillville is located on what used to be woodland that belonged to the Potawatomi Indians. In 1834, a clearing was created for ceremonial purposes and was called McGwinn Village. A year later, a white man by the name of Jeremiah Wiggins settled in the place; McGwinn Village thus gave way to Wiggins Point.[7]

Under the name Wiggins Point, the place became a well-known stop for wagon trains heading to Joliet, Illinois along the old Sauk Trail (also called the Sac Trail), which was an old Indian trail. At one time, 16 trails radiated outward from Wiggins Point. In 1838, Wiggins died. Sometime afterwards, local settlers renamed the place Centerville. Later still, it was renamed Merrillville after the brothers Dudley and William Merrill.[7] Dudley Merrill operated a hotel and store in Centerville, and his son John P. Merrill was a Township Trustee.[8]

Nearby, in the same former hunting grounds of the Potawatomi Indians, other settlements had sprung up. Near Deep River creek was a settlement named Deep River; near Turkey Creek was another settlement with that creek's name. Other settlements included Ainsworth, Lottaville, and Rexville. At one time, the post office for the area was named Lottaville.

In 1848, all of these settlements, including Merrillville (that is, the old McGwinn Village) were collected into one and called Ross Township. As time went by, bits and pieces of Ross Township were taken by Hobart and Crown Point when those towns incorporated.

In 1971, the area officially became Merrillville (which now includes the old Merrillville as well as other settlements nearby) and was incorporated as a town under Indiana law.[7] During this time, the majority of the town's growth was due to white flight from Gary.[9]

In 1993, Merrillville tried to annex unincorporated Winfield Township to get more land. The residents blocked Merrillville by creating the town of Winfield.[10]

Purdue Technology Center at Ameriplex at the Crossroads in Merrillville

In 2009, a pedestrian bridge at Hidden Lake Park collapsed, injuring at least 25 people.[11] The catastrophe occurred around 10 PM after the annual Fourth of July fireworks display,[12][12] when several dozen people attempted to cross the wood suspension bridge.[13] Police officers stationed at either side of the bridge were unable to stop the advancing parkgoers, and with numerous people jumping up and down the 30-year-old bridge collapsed, sending somewhere around fifty people into the waters of Hidden Lake.


Merrillville is a hub for retail trade in Northwest Indiana. The US 30 corridor between Taft Street and Colorado Street harbors a large concentration of big-box retailers, hotels, restaurants, and automobile dealerships.

Ameriplex at the Crossroads, an industrial and technology park, opened at Broadway between 93rd Avenue and 101st Avenue in 2005. The development is designated an Indiana Certified Technology Park and includes two Purdue University related facilities: Purdue University Calumet's Academic Learning Center and a business incubator/technology center operated by the Purdue Research Foundation.

Heavy industry such as steelmaking and petroleum refining that characterizes the economy of northern Lake County does not have a significant presence in Merrillville.

The town is home to the corporate headquarters of NiSource, a Fortune 500 company, and of Centier Bank, the largest privately-owned independent bank in Indiana.[14]
