Pilkington Brothers works, founded in 1826, dominates the town's industrial quarter and still produces all the UK's output of flat glass. In 1994, planning permission was sought out for a link road connecting the M62 directly with the town centre. The development included a £5m retail and commercial property project in the Ravenhead area that had seen successive business closures with the folding of UGB and Ravenhead Glass. Retail The town's shopping area is centred on the parish church of St Helens, the original site of St Mary's open market. The open market was later replaced by an awned covered market that populated Chapel Lane and the locale. The current Church Square shopping centre surrounds St Helens on three sides. Church Street, the main high street, runs parallel to Church Square and is sandwiched by the town's second shopping centre known as The Hardshaw Centre. The other main shopping streets in the town centre include the more traditional small store based Bridge Street, Duke Street and Westfield Street populated by independent specialists. Church Square was bought by St Helens Council in 2017 for £26.6m as part of local regeneration plans. The town centre has several supermarkets including mainstream stores such as Asda and Tesco, as well as smaller stores such as Lidl. Morrisons retain two stores located in the Eccleston and Sutton areas of the town. There is also a Tesco superstore in Earlestown, which is on a former Safeway site and many smaller Tesco Express and Tesco Metro stores. A new Tesco Extra store opened in October 2011 on the outskirts of the town centre to replace the existing Chalon Way superstore, which has now been taken over by new retail Home & Leisure outlet, The Range. St Helens has two major retail parks, one on either side of the St Helens Linkway. The older of these, St Helens Retail Park, is home to several discount stores and wholesale retailers. The larger Ravenhead Retail Park houses more large-scale mainstream retail stores, and a number of restaurants, fast food outlets and cafes. The same area (in particular the old United Glass Bottles site) has been used for development of the new St Helens RLFC stadium and the construction of a Tesco Extra supermarket, to replace the smaller Tesco supermarket in the town centre. At 140,000 square metres, this Tesco Extra store is one of the biggest in England Major investment
