When the Main Stand was built, it provided a new changing room facility and gymnasium for the players, replacing the smaller, outdated ones at the old Pavilion End of the ground, next to the scoreboard.

This was because the old Eccleston railway ran below the site of the new stand, linking the Triplex (Pilkington) factory to the town centre.

When St Helens were on television, the Popular Stand regularly were heard singing and chanting due to the small distance between the cameras and the supporters.

Prior to being moved to the Family Stand, the changing rooms were at the Dunriding Lane End and players would enter from a tunnel.

The Dunriding Lane End of the ground was known as the Boys' Pen – a spot where die-hard fans congregated during the post-war years.

A ground record of 35,695 fans turned up to watch Saints play Wigan on Boxing Day 1949.

In February 1951, the newly completed Eccleston Kop covered enclosure was opened and was named after Supporters' Club Secretary George Eddington.

The bar and restaurant complex was opened at Dunriding Lane End of the Knowsley Road stadium in 1973.

On the club's new sponsorship deal with Earth Money, the stadium got new signs, new dug outs were installed, as were the toilet facilities which had been long complained about by supporters.

In June 2007, club chairman Eamonn McManus announced plans for a new 18,000 capacity stadium, with a Tesco store and plaza with 2,000 car parking spaces for the 2011 Super League Season.

The last first team match at Knowsley Road was the St. Helens vs Huddersfield game, a play-off semi-final on 24 September 2010.

St. Helens won 42–22, the final try on the ground being scored by retiring club captain Keiron Cunningham.
